Richard Strange and Charles Zamorano pleaded guilty to violating 21 U.S.C. §§ 841(a)(1), 846 (1994), by conspiring to distribute and possess with intent to distribute controlled substances. Strange and Zamora-no appeal the sentences imposed by the district court, 1 and we affirm.
I. BACKGROUND
In February of 1993, Strange, a drug dealer, told his friend and customer Robert Scott that he had located a connection for guaranteed quantities of marijuana, and in subsequent conversations Strange disclosed that Zamorano was his supplier. A few months later, Strange inquired whether Scott would be willing to accept delivery of a package from El Paso, Texas containing marijuana. In exchange, Strange agreed to forgive Scott’s $50 outstanding balance and to give Scott a discount on future narcotics purchases. Scott consented to this arrangement, and during the first week of July in 1993 a shipment of approximately five pounds of marijuana arrived at his home. Scott received a second parcel from El Paso, also consisting of about five pounds of marijuana, in the middle of that month. On both occasions, Strange promptly travelled to Scott’s house and retrieved the contraband.
In late July of 1993, members of the El Paso Airport Drug Task Force, acting in response to a call from an employee of the United Parcel Service, intercepted a package addressed to Scott’s Kansas City residence. The officers located inside the carton 239.5 grams of cocaine hidden within a pair of cowboy boots. On August 2, 1993, after con *359 ducting a controlled delivery of the box to its intended destination, federal agents arrested Scott. Scott agreed to cooperate with law enforcement personnel, and he provided information indicating that Zamorano transferred drugs to him from El Paso; Scott further divulged that Strange was responsible for taking possession of the narcotics and wiring the illicit proceeds back to Zamorano. In fact, an investigation revealed that various wire transfers were made to Zamorano from a man in Kansas City using the name “Bob Scott.” A handwriting expert concluded that Strange was the person who had signed as “Bob Scott” to authorize the transfers, and documents on file at Western Union positively identify Zamorano as the individual who collected the wired funds in Texas. In total, approximately $14,410 passed from Kansas City to El Paso during the relatively short life of the machination.
On June 26, 1995, a federal grand jury issued a four count indictment against Strange and Zamorano. Both men pleaded guilty to the first count in the indictment, 2 which described a conspiracy to distribute and possess with intent to distribute illegal drugs in violation of 21 U.S.C. §§ 841(a)(1), 846, in return for the Government’s pledge to dismiss the remaining charges against them. At sentencing, both defendants denied knowledge that the third delivery contained cocaine instead of marijuana, and Scott testified that no one had ever told him what would be included in that final shipment. Nonetheless, the district court, over defense objections, held Strange and Zamorano accountable for the quantity of cocaine found in the parcel.
In this appeal, Strange and Zamorano contend the district court committed error when it found they could have reasonably foreseen that the package addressed to Scott might be laden with cocaine. In addition, Strange argues the district court inappropriately calculated the criminal history points assessed against him. We consider these points seria-tim.
II. DISCUSSION
A. Relevant Conduct
To arrive at the appropriate sentencing range for a drug defendant, it is invariably necessary for the district court to reference the “relevant conduct” provisions of the United States . Sentencing Guidelines.
See United States v. Hayes,
Strange and Zamorano now assert, as they did before the district court, that the Government has failed to prove the scope of their conspiracy extended to encompass cocaine. Rather, the dealers maintain the evidence shows that they contrived to exclusively distribute marijuana. Similarly, given the limited nature of their enterprise, they declare that it could not have been reasonably foreseeable to them that the pertinent package would include cocaine. For-these reasons, they contend that the district court incorrectly augmented their sentences by incorporating cocaine into the amount of drugs attributable to them. We will reverse only if the district court committed clear error when ascertaining drug quantity.
See United
*360
States v. Smith,
Before moving to the merits of this issue, we pause to reflect upon the conduct to which Strange and Zamorano have admitted or that the Government proved by a preponderance of the evidence. It is beyond cavil that both conspirators played instrumental roles in orchestrating the transportation of the package in question. Strange introduced Zamorano and Scott, and he concedes that he acted as a “facilitator” for the various narcotics shipments. To be sure, his awareness of the final conveyance is evidenced by a phone call he made to Scott during which he queried whether the parcel had arrived. Likewise, Zamorano confirms that he arranged the delivery through his “source” in El Paso. Thus, though Strange and Zamorano acknowledge considerable involvement with the illegal mailing, each of the confederates professes to have believed that the carton would contain marijuana, not cocaine. 3
Within this factual coiitext, we are persuaded that it would have been more fitting to assess the conspirators’ responsibility for the cocaine under Guideline § 1B1.3(a)(l)(A). 4 Unlike paragraph (a)(1)(B), which the district court utilized to hold Strange and Zamorano hable for the “acts and omissions of others,” paragraph , (a)(1)(A) appertains to conduct personally undertaken by the defendant being sentenced. 5 See U.S. Sentencing Guidelines Manual § 1B1.3(a)(1) (1995). For instant purposes, the following elaboration within the Guideline’s application notes is of particular moment:
With respect to offenses involving contraband (including controlled substances), the defendant is accountable for all quantities of contraband with which he was directly involved....
The requirement of reasonable foreseeability applies only in respect to the conduct (i.e., acts and omissions) of others under subsection (a)(1)(B). It does not apply to conduct that the defendant personally undertakes ...; such conduct is addressed under subsection (a)(1)(A).
U.S. Sentencing Guidelines Manual § 1B1.3 application note 2 (1995). Simply stated, reasonable foreseeability is significant solely when evaluating relevant conduct under § lB1.3(a)(1)(B); it is completely immaterial to the analysis guided by § 1B1.3(a)(1)(A).
6
See United States v. Lockhart,
Mindful of these precepts, we have no difficulty in determining that the district court correctly attributed the 289.5 grams of cocaine to Strange and Zamorano! Through their own actions, the two men aided, abetted, and wilfully caused the conveyance to Scott of at least three packages.
See
U.S. Sentencing Guidelines Manual § 1B1.3(a)(1)(A) (1995). Their convictions verify that they embarked upon this behavior with the requisite criminal intent and with every expectation of receiving some type of illegal drug to distribute. Accordingly, under the scheme sanctioned by Congress, and without regard to reasonable foreseeability, they are accountable at sentencing for the full quantity of all illegal drugs located within the parcels.

See id.
§ 1B1.3 application note 2, illus. (a)(1) (suggesting that a drug defendant is chargeable at sentencing for any narcotic with which he was directly involved “regardless of his knowledge, or lack of knowledge of the actual type or amount of that controlled substance”);
United States v. Salazar,
B. Strange’s Criminal History Category
Strange additionally propounds that the district court committed a number of errors in calculating his criminal history category. “We review de novo the district court’s construction and interpretation of Chapter Four of the Guidelines, and we review for clear error the district court’s -application of Chapter Four to the facts.”
United States v. Jones,
1. Strange’s prior sentences as “related cases”
A defendant’s criminal history category is dictated by the amount of criminal history points levied against him. In large measure, the sum of criminal history points is linked to the defendant’s “prior sentences.” See U.S. Sentencing Guidelines Manual § 4A1.1 (1995). Although the Guidelines direct a district court to assess separate points for prior sentences decreed in unrelated cases, they further instruct that “[pjrior sentences imposed in related cases are to be treated as one sentence.” Id. § 4A1.2(a)(2).
Because many of Strange’s manifold past convictions were consolidated for sentencing, he asked the district court to treat those adjudications as related cases under the Guidelines. The court denied this request, however, based on a 1991 amendment to the application notes which specifies that “[pjrior sentences are not considered related if they were for offenses that were separated *362 by an intervening arrest (i.e., the defendant is arrested for the first offense prior to committing the second offense).” U.S. Sentencing Guidelines Manual § 4A1.2 application note 3 (1995). Strange does not deny that his previous sentences were for offenses separated by intervening arrests, but he still insists that the district court should have used the pre-1991 version of the Guidelines when tallying his criminal history points.
This assertion is untenable. We'have often held that “the sentencing court should apply the Sentencing Guidelines in effect at the time of sentencing -unless the court determines that such application would violate the ex post facto clause.”
United States v. Cooper,
2. Strange’s prior uncounseled conviction
Strange did not have legal representation in 1989 when the State of Missouri convicted him for possession of under 35 grams of marijuana. He now protests that he did not make a knowing and intelligent waiver of counsel , in that case. Hence, according to Strange, the district court committed error when it assessed a criminal history point applicable to that offense.
Normally, defendants are not permitted to use a federal sentencing proceeding as a forum to challenge a prior conviction.
See
U.S. Sentencing Guidelines Manual § 4A1.2 application note 6 (1995)(explaining that the district court should not count sentences resulting from convictions ruled constitutionally invalid “in a prior case”);
United States v. Jones,
3. Strange’s conviction for driving a motor vehicle with excessive blood alcohol content
In 1990, a state court sentenced Strange for driving a motor vehicle with excessive blood alcohol content, and we summarily rule that the district court properly added a criminal history point for that offense. U.S. Sentencing Guidelines Manual § 4A1.2 application note 5 (1995)(“Convictions for driving while intoxicated or under the influence (and similar offenses by whatever name they are known) are counted. Such offenses are not minor traffic infractions within the meaning of § 4A1.2(c).”). Contrary to Strange’s characterization of Missouri’s law, driving a motor vehicle with excessive blood alcohol content is absolutely not a lesser included offense of driving while intoxicated.
See State v. Robertson,
III. CONCLUSION
The district court properly calculated the quantity of drugs attributable to Strange and Zamorano, and it committed no error in determining Strange’s criminal history category. • As such, we affirm the sentences in this case.
AFFIRMED.
Notes
. The HONORABLE FERNANDO J. GALTAN, JR., United States District Judge for the Western District of Missouri.
. Although the plea agreements were similar, they differed in at least one respect warranting brief comment. Specifically, Strange pleaded guilty to conspiring to distribute marijuana. Za-morano, on the other hand, admitted in his plea that he conspired to distribute a "controlled substance.”
. The appellants proffer quite different explanations for the presence of the cocaine within the package. Strange speculates that Zamorano, without consulting either of his associates, might have taken it upon himself to include cocaine in the shipment. Zamorano, of course, does not join in this postulation, but instead posits that his "source” probably sent the wrong box to Scott’s address. ' It is worth mentioning that, to date, Zamorano has not identified his "source.”
. The district court did not address paragraph (a)(1)(A) at sentencing, but it is well established that we may affirm a-defendant’s sentence on any ground supported by the record.
See United States v. Garrido, 995
F.2d 808, 813 (8th Cir.),
cert. denied,
. We emphasize that it is wholly appropriate to employ paragraph (a)(1)(A) even when, as here, the defendant being sentenced stands convicted of a conspiracy only.

.To the degree that our opinion in
Hayes,
. To qualify as relevant conduct under § lB1.3(a)(l), the act or omission must also have occurred, among other, impertinent alternatives, "during the commission of the offense of conviction.” U.S. Sentencing Guidelines Manual § lB1.3(a)(l) (1995). The Government has satisfied this prerequisite in the current appeal. We have previously interpreted the term “offense of conviction” to mean "the substantive offense to which the defendant pleads guilty,"

v.
Morton,
. We realize that Strange might intend to argue that the pre-1991 Guidelines should apply because his
prior
offenses occurred before that date. This allegation is implausible.
Cf. United States v. Allen,
. Strange also avers that the district judge should not have included this offense in his criminal history score because the state court merely imposed a fine, and no jail time, for the conviction. Strange is mistaken. Section 4Al.l(c) of *363 the Guidelines is explicitly designed to apply to prior sentences in which only a fíne was ordered. See U.S. Sentencing Guidelines Manual § 4A1.1 background at 256 (1995)(“Subdivisions (a), (b), and (c) of § 4A1.1 distinguish confinement sentences longer than one year and one month, shorter confinement sentences of at least sixty days, and all other sentences, such as ... fines.... ”).
