Ben Klein (Klein) was convicted of five counts of tax evasion in 1973. Related to those prior convictions, there are now two consolidated appeals before us, one challenging the trial court’s denial of a petition for a writ of coram nobis (No. 87-1769) and one challenging the trial court’s denial of a Rule 60(b) motion for a new trial in that proceeding (No. 88-2692). We affirm both rulings.
I
Factual Background and Procedural Posture
The lengthy and complex procedural posture of this case is relevant to both of these appeals. Klein’s petition for a writ of
cor-am nobis
challenges his 1973 convictions under 26 U.S.C. § 7201 for evading taxes from 1966-1970. We affirmed those five convictions in 1975.

A.
Klein’s 1978 Motion for a New Trial
In 1978 Klein filed a motion for a new trial in his criminal case on the ground of newly discovered evidence. The evidence consisted of information known to the Bureau of Narcotics and Dangerous Drugs (B.N.D.D.) and the I.R.S. before trial and not communicated to Klein. Klein had been investigated for possible involvement in narcotics trafficking. During the early part of its investigation the B.N.D.D thought that he had received income from financing narcotics deals. This belief was referred to the I.R.S., which ultimately decided not to pursue the matter. YII R. 166-167. The trial court denied Klein’s motion for a new trial, reasoning that it was untimely and that none of the new evidence would have been admissible or exculpatory.
United States v. Klein,
No. 73-CR-ll (D.Colo. April 10, 1978). Again we affirmed.

B.
Disciplinary Proceedings Before the Colorado Supreme Court
Throughout the 1970’s and 1980’s Klein was involved in state bar disciplinary proceedings. In 1972, he was suspended from the practice of law for an indefinite period of time, but in no event for less than three years, for fabricating documents and presenting them to the Colorado Supreme Court Grievance Committee in defense of pending allegations of professional misconduct.
See People v. Klein,

Civil Proceedings in the Tax Court
In 1980 Klein received a notice of deficiency in income tax and additions to tax for civil fraud penalties from 1962 through 1970. The Tax Court found that the government had failed to prove fraud for the years 1962 through 1965, but reasoned that Klein was collaterally estopped by his criminal convictions from denying fraud for 1966 through 1970.
Klein v. Commissioner,
48 TCM 651 (1984). Klein’s appeal to this court of the Tax Court’s decision (No. 85-1245) has been abated pending disposi
*253
tion of these consolidated appeals. Our opinion affirming the Tax Court is being separately filed today.
D.
Denial of the Writ of Coram Nobis
In support of his petition for coram no-bis relief in the district court Klein argued that: (1) there was new evidence that the government withheld its belief that he was financing narcotics deals; and (2) there was new evidence that Chief Probation Officer Hyland had knowledge of Klein’s mental condition, which both he and the prosecutors failed to disclose. After hearing testimony and receiving numerous exhibits, the trial court denied the petition. IX R. 2-7.
In his oral ruling the district judge found: (1) that Klein had the burden of proof; (2) that Klein delayed seeking the writ from 1978 to 1985 to the government’s prejudice; (3) that the prosecution did not know of Hyland’s information before trial and therefore had no duty to divulge it; (4) that Hyland, as a probation officer of the court, had no duty to divulge his knowledge of Klein’s mental illness in the navy; (5) that the government’s belief that Klein was financing narcotics deals was not exculpatory; (6) that the affidavits of Klein’s 1973 trial attorneys, stating that the drug information would not have made a difference, were highly persuasive; (7) that introduction of the drug evidence would have been sheer folly; and (8) that Klein had failed to carry his burden of proof. IX R. 2-7. A timely notice of appeal was filed.
E.
Denial of the Motion for a New Trial
As noted, in 1988 the Colorado Supreme Court granted Klein’s petition for reinstatement to the practice of law, finding that he had regained his mental health and was competent to practice law.

Analysis
A
Denial of the Petition for a Writ of Coram Nobis
While the writ of
coram nobis
was abolished by the 1946 amendment of Fed.R. Civ.P. 60(b) in civil cases, it retains its vitality in criminal proceedings.
United States v. Morgan,
It is presumed that the proceedings leading to the conviction were correct,
see Morgan,
i
Evidence Of Klein’s Involvement in Narcotics Trafficking
The court held an extensive evidentiary hearing before denying the coram nobis petition. Klein produced evidence (much of it the same as that produced in the 1978 motion for a new trial and the tax case) of the B.N.D.D.’s investigation and the allegedly unwarranted suspicion held by it and the I.R.S. that he had received income from financing narcotics deals. He argued that if the government had disclosed its suspicion prior to trial, he could have introduced that evidence and shown the government’s suspicion unfounded, thereby undermining the soundness of the government’s investigation and its decision to charge him.
We reject Klein’s argument for fundamental reasons. Klein failed to exercise due diligence in seeking the writ, a prerequisite to relief.
See Hirabayashi v. United States,
Even assuming the exercise of due diligence, Klein’s argument fails on the merits. It is important to remember that Klein’s argument in support of his petition for a writ of
coram nobis
is premised upon an alleged denial of his constitutional right to a fair trial — on the ground that the prosecutors failed to disclose impeachment evidence under
Brady v. Maryland,
Moreover, Klein failed to carry his burden in this
coram nobis
proceeding of demonstrating that the new evidence “would have likely led to a different result,”
Scherer,
It is true that there was testimony from several witnesses that the use of the evidence might have resulted in a different charge against Klein or a different verdict on the tax evasion charge. 4 But there were also affidavits from Klein’s trial attorneys (attorneys Wald, Bugdanowitz and Abramovitz) stating that the evidence would not have changed their presentation of the defense. Appellee’s Addendum, pp. 93-96. While these affidavits were prepared in 1978 in connection with the motion for a new trial and without all the information which subsequently became available, they were admitted below and the trial court found them persuasive, along with the other evidence presented at the hearing. IX R. 5. I.R.S. attorney Gehres, the government’s summary witness in the criminal trial, testified that the drug evidence would not have made a difference. VII R. 160-162, 165-167. And prosecutors Madden and Spelts also testified that the drug evidence would not have changed the outcome. VII R. 187, 202, 207-208. We note that the government did not introduce any evidence relating to the drug accusations at trial. 5 VII R. 221-224.
Having considered all the evidence, the trial court concluded that it would have been the “sheerest folly for defense counsel, Klein’s defense counsel, to have introduced the subject of narcotics_” IX R. 5. As a matter in the factual area of trial strategy and evaluation of evidence by counsel, we do not think this finding is clearly erroneous.

We agree with Klein’s
*256
position that in assessing the possible impact of withheld evidence on a jury, and the materiality of the evidence, we should apply the
de novo
review standard.
Cf. Chaney v. Brown,
ii
Evidence Relating to Klein’s Competency
Klein argued in his criminal trial that he did not have the mental capacity to form the requisite intent to defraud and that he was legally incompetent. James Hyland (who had a master’s degree in psychology but was not a trained psychiatrist) worked as chief pharmacist at a psychiatric observation unit in the Navy and observed Klein for six to eight weeks during 1945, the year of Klein’s discharge. Hyland was the Supervising Probation Officer for the District of Colorado at the time of Klein’s criminal trial and later became Chief Probation Officer. Hyland did not testify in the 1973 trial, but he did testify before the Tax Court by deposition (this testimony was admitted at the coram nobis proceeding below) and during the August 1985 hearing on the petition for a writ of coram nobis.
Hyland said that during his World War II service Klein was unable to function militarily, was disorganized, bewildered, hostile, and at times unaware of what was going on. Appellant’s Addendum, pp. 30-31. He testified that Klein was diagnosed as schizophrenic, although this diagnosis was later changed to “personality disorder.” Id. at 28. At the criminal trial Doctor Miller, the court appointed psychiatrist, testified that while Klein was mentally ill he had the requisite mental capacity to form specific intent to defraud. VII R. 9. In forming this opinion, Doctor Miller relied in part on the apparent absence of naval records which might indicate that Klein suffered from a mental illness. VII R. 15. Miller said, however, that even had he known of Hyland’s observations in the Navy, his findings regarding Klein’s competency in 1973 “would not [have] been altered by Mr. Hyland’s testimony in any way.” VII R. 10.
Klein argues that Hyland’s testimony would have helped to demonstrate a history of mental illness, thereby bolstering Klein’s defense of mental incapacity and avoiding any claim that the mental incapacity defense was recently contrived. The argument fails because the evidence shows that Klein had knowledge of Hyland’s information through his attorney, Mr. Wald, .if not through his own experience with Hyland in the Navy. 7 The parties stipulated that Hy-land talked with Wald prior to the criminal trial and that Wald was informed that Hy-land knew Klein while in the Navy. IV R. 13. Hyland states in his affidavit of March 13, 1985 that he discussed his knowledge of Klein’s background with Wald prior to the criminal trial. I R. 7, Exh. C. Hyland also testified at the August 1985 hearing that he had met with Wald prior to the criminal trial and discussed Klein’s mental condition in the Navy. IV R. 18-26, 34-35. Furthermore, attorney Wald, in a letter to the Justice Department (dated December 22, 1972 and preceding the 1973 trial), makes reference to Klein’s “long-existing psychotic condition” and to his “psycho discharge from the navy.” I R. 7, Exh. D. And Wald himself sent a copy of a letter from Klein’s psychiatrist to the Justice Department on January 11, 1973, in which Klein’s psychiatrist states that obsessions and compulsions caused Klein’s discharge from the Navy. I R. 7, Exh. E.
*257
While the trial court did not specifically find that Klein had knowledge of the information on his mental condition in the Navy, we think the record plainly establishes such knowledge and precludes an argument that Klein has demonstrated, as he must, a complete miscarriage of justice.
Williamson,
Perhaps most importantly, Miller (whose testimony in 1973 was particularly important) testified at the
coram nobis
hearing that even had he known of Hyland’s information, he still would have testified in 1973 that Klein was competent. VII R. 7-10,12, 21-22. This undercuts Klein’s argument that Hyland’s testimony would likely have made a difference and, as noted earlier, that is the burden Klein carries here.
Scherer,
Klein’s remaining arguments in appeal No. 87-1679 are without merit. His repeated references to our opinion in

Rule 60(b)(5)

proceeding. The motion was based upon the Colorado Supreme Court’s decision in

Reply Brief, p. 3-5. The standard for relief under this portion of Rule 60(b)(5) is an exacting one and requires a strong showing. Wright & Miller,
Federal Practice & Procedure:
Civil § 2863, pp. 207-208 (1973). The rule is not a substitute for appeal.
Schildkaus v. Moe,
Klein’s argument is based upon an unwarranted characterization of the evidence at the 1973 tax evasion trial. Klein argues that the government introduced
People v. Klein,
It is true that
Klein II
says: “The evidence adduced at the hearing established that the respondent suffered from a serious mental illness from his teenage years through at least 1973, was still suffering some effects from that illness and at the date of the hearing was only marginally competent to proceed.”
Klein II,
Assuming that
Klein I
was admitted in the 1973 criminal trial and was relied upon as Klein argues,
11
we think the district court was well within its discretion in denying the motion for a new trial in the
coram nobis
proceeding.
Navajo Tribe of Indians v. New Mexico,
Klein also exaggerates the importance of Klein I to Miller’s testimony in the criminal trial to show mental capacity. We note that Klein I does not mention the issue of *259 mental capacity. At the criminal trial, both sides introduced substantial evidence on that issue, as our affirmance of Klein’s conviction makes clear. 12 Klein does not (and cannot now) dispute that evidence, but instead gives unwarranted focus to the importance of Klein I to Doctor Miller’s testimony. Any references to Klein I by Doctor Miller to show that Klein’s behavior was caused by disciplinary proceedings was not a fundamental part of the prosecution’s case so that the new determination in Klein II calls for a new trial under Rule 60(b)(5) from the denial of coram nobis relief.
Moreover,
Klein II
addressed the petition for reinstatement and discussed competency for professional practice. Indeed, the court specifically noted that a defense “based on the respondent’s mental condition during the years 1966-1970 had been raised by the respondent during his federal tax evasion trial and had been rejected by the jury.”

Rule 60(b)(6)
Alternatively, Klein argues that relief should have been granted under Rule 60(b)(6) and its “grand reservoir of equitable power to do justice in a particular case.”

Notes
. We note also that

relief is not available to litigate issues already litigated; it is reserved for claims which have yet to receive their first disposition.
United States v. Keane,
. It is true that
Brady
requires disclosure of impeachment evidence as well as exculpatory evidence if that evidence is both favorable to the accused and material to guilt or punishment.
United States v. Bagley,
Viewing the drug evidence in the context of the entire record,
see Trujillo v. Sullivan,
.The trial court here reasoned that the evidence "probably would have been devastating in terms of the jury’s attitude toward Klein generally.” IX R. 6. We agree. Evidence that a criminal defendant had financed drug deals would be dubious evidence to introduce on his behalf, if admissible at all. See e.g. Fed.R.Evid. 403.
. Attorney Abramovitz, who participated in Klein’s defense in 1973 and who submitted an affidavit in connection with the motion for a new trial in 1978, said that his conduct in the case might have been different had he known about the drug evidence. VIII R. 254-256. Attorney Haddon said that the drug evidence would have made a difference and might have resulted in a different charge. IV R. 57, 69-70. Attorneys McAllister and Drexler (who practiced with Wald) also said the drug evidence might have resulted in a different charge or a different verdict. IV R. 66-67; VIII R. 273-274. Additionally, Judge Winner (a former United States District Court Judge and Chief Judge of the District of Colorado — now resigned) testified that the drug evidence and Hyland’s testimony combined would probably have made a difference in the verdict. VIII R. 280-282. And the parties stipulated that former United States Attorney Henry would have testified, if called, that he would join Mr. Drexler, Judge Winner and Mr. Abramovitz in saying "with these events that he believes there could have been a different verdict." VIII R. 309.
We note that of these witnesses Abramovitz was the only one who was involved in Klein’s 1973 trial. The others, including Judge Winner and former United States Attorney Henry, testified only as experts after reviewing materials provided by Klein’s attorney.
. This undisputed fact is particularly significant. Klein argues that the drug evidence is relevant for impeachment purposes. However, no evidence was presented at trial in 1973 that he was involved in narcotics trafficking. This new evidence, therefore, could only be used to impeach the soundness of the government’s overall case, to show that the government’s summary witness had erred in stating that no mistakes had been made, or to show that the government had a mistaken belief during its pre-trial investigation. We do not think that any of these impeachment purposes demonstrate a complete miscarriage of justice.
Moreover, Klein cannot attack the indictment here on the grounds asserted.
Cf. Bank of Nova Scotia v. United States,
— U.S. -,
. We reject Klein’s argument that the trial court’s factual findings and conclusions are inadequate in form under Fed.R.Civ.P. 52(a). After hearing numerous witnesses and reviewing many exhibits the court made specific findings and conclusions. IX R. 2-7. These oral findings and conclusions are in accordance with Rule 52(a) and sufficiently indicate the factual basis for the court’s ultimate conclusion.
Colorado Flying Academy, Inc. v. United States,
. Because Klein should be held to have had knowledge of Hyland’s information prior to trial through his attorney, we need not reach Klein's argument that Hyland had a duty to reveal his knowledge of Klein to the court.
. Abramovitz said that he would find it difficult to believe that Hyland's testimony would not have made a difference to the jury. VIII R. 244-245. Attorney Haddon said Hyland’s testimony would have made a difference. IV R. 57. Attorneys McAllister and Drexler said Hyland’s testimony might have resulted in a different verdict. IV R. 66-67; VIII R. 273-274. Additionally, Judge Winner testified that Hyland’s testimony, combined with the drug evidence, probably would have have made a difference in the verdict. VIII R. 280-282. And the parties stipulated that former United States Attorney Henry would have testified, if called, that Hy-land's testimony could have resulted in a different verdict. VIII R. 309.
. Rule 60(b) provides in part that:
On motion and upon such terms as are just, the court may relieve a party ... from a final judgment, order, or proceeding for the following reasons: ... (5) the judgment has been satisfied, released, or discharged, or a prior judgment upon which it is based has been reversed or otherwise vacated, or it is no longer equitable that the judgment should have prospective application....
. Klein is not arguing that "a prior judgment (Klein I) upon which it (the denial of coram nobis relief) is based has been reversed or otherwise vacated_” Rule 60(b)(5). Such an argument would fail because this application of 60(b)(5) is limited to cases in which the present judgment is based on the prior judgment in the sense of res judicata or collateral estoppel. It does not apply merely because a case relied on as precedent by the court in rendering the present judgment has since been reversed. Wright & Miller, Federal Practice & Procedure: Civil § 2863, p. 204 (1973). It is undisputed here that Klein I was not the basis of the denial of the petition for a writ of coram nobis in the sense of res judicata or collateral estoppel.
. The government contends Klein I was referred to but not admitted. Klein argues that the government admitted in its response to his motion for a new trial in the district court that Klein I was introduced into evidence. We will assume (without deciding this dispute over the state of the record) that Klein I was admitted in the tax evasion criminal trial.
. As we noted in our 1975 opinion affirming Klein’s conviction:
Two psychiatrists and two psychologists testified that Klein was not legally competent at the time of the offense. Their general diagnosis was that he was an obsessive-compulsive, paranoid schizophrenic. In addition, twelve lay witnesses and a handwriting expert gave testimony of erratic behavior and other incidents to support a finding of incompetency. This, of course, rebutted the presumption of sanity and the burden was on the Government to prove competency, which it undertook to do. Competency thus became an element of the offense as it had been for all practical purposes from the outset. United States v. Bettenhausen,499 F.2d 1223 [34 AFTR 2d 74-5415] (10th Cir.); Wion v. United States,325 F.2d 420 (10th Cir.).
Three psychiatrists and one psychologist testified as part of the Government’s case that while Klein was possibly mentally ill, he was competent at the times the offenses were committed. This testimony was supported by that of several lay witnesses. What Klein asserts is that the evidence in favor of incompetency is so overwhelming that it was error to allow the question to go to the jury. We cannot agree.
