In this diversity case, Gaylon Hofer (“Hofer”) brought suit against Mack Trucks, Inc. (“Mack”), alleging negligence and strict liability in the design, manufacture, testing, and marketing of a Mack truck and seeking punitive damages. Hofer appeals the judgment, entered upon a jury verdict that Hofer is not entitled to any recovery, and from the district court’s 1 denial of Hofer’s Motion for a New Trial. On appeal, Hofer asserts that the court erred with regard to a discovery ruling and several evidentiary rulings, in its refusal to submit the issue of punitive damages to the jury, and in its refusal of certain proposed jury instructions. Hofer further asserts that the closing argument of counsel for Mack was prejudicial. We affirm the judgment of the district court.
I.
FACTS
Hofer was rendered a paraplegic as a result of the rollover of a newly designed, 1985 Mack truck on October 11, 1985. The sleeper compartment mattress sits on two removable base panels which are not secured; under each base panel is a storage compartment, designed to allow inside access from the sleeper compartment. Hofer was asleep in the sleeper compartment of the cab, face down with his head behind the *380 driver’s seat, when the truck left the highway, rolled onto its right side and skidded to a stop. At trial, Hofer presented the theory that the mattress and the left base panel dislodged during the accident, allowing a heavy tool box to eject from within the storage compartment into the sleeper compartment, striking Hofer in the chest, and causing a cord lesion and the resultant paralysis.
Mack presented evidence refuting Hofer’s causation theory. Mack argued that Hofer flew off the mattress and fell seven to ten feet to the right side of the truck, landing on his buttocks. The force exerted on his spine caused a compression fracture and, as he then flexed forward, the spine was severed, causing paralysis. Mack further contended that the mattress was between Hofer and the storage compartment, shielding him from the toolbox.
II.
DISCOVERY
Predecessor Truck Designs
The subject Mack truck was a Model MH. Hofer sought discovery relating to predecessor designs (specifically Models F and W) manufactured since 1975, citing numerous design and materials changes. Hofer desired to discover information which would support a showing that Mack departed from a prior, safer design, the reasons for the departures, and any comparisons by Mack of the crashworthiness and safety of the models. Hofer’s motion to compel was denied by the district court, which essentially stated that the requested materials were neither relevant nor discoverable.
Rule 26(b) of the Federal Rules of Civil Procedure is widely recognized as a discovery rule which is liberal in scope and interpretation, extending to those matters which are relevant and reasonably calculated to lead to the discovery of admissible evidence.
Kramer v. Boeing Co.,
In this case, Hofer articulated two reasons for discovery about Mack’s predecessor designs and the departures therefrom. Hofer refers to a nonspecific allegation that the change in overall construction, from reinforced steel and aluminum to fiberglass, affected the general crashworthiness of the model MH truck. More specifically, Hofer states that, “The matter of a departure from a fully enclosed storage compartment in constructing the MH model truck cab was at the core of Hofer’s claim.” Brief for Appellant at 27.
First, it is clear that the differences and departures in the design of the storage compartment were fully explored at trial. (It should be noted that Mack did agree to produce the designs, diagrams, and blueprints of the bunk base (storage compartment) portion of the predecessor models. The record reflects this agreement; whether or not the production actually took place is not clear from the record before us.) Second, two of Hofer’s experts independently located, examined, and photographed actual F and W truck models. In addition, Hofer’s primary expert stated that he saw diagrams of the two predecessor models. The differences in construction were thus examined and analyzed, and were explained to the jury at trial.
In previous cases, decided in a variety of jurisdictions, the courts have set forth no black letter rule of law regarding discovery of predecessor models in products liability cases, other than to state that discovery of similar, if not identical, models is generally
*381
permitted.
Culligan,
Sufficient similarities have been found to exist where it was alleged that three-wheel all-terrain vehicles are inherently unstable,
Culligan, supra;
where a plaintiff maintained that a redesigned motor mount that failed in his car had not eliminated the defects found in earlier models,
Swain v. General Motors Corp.,
In the instant case we are satisfied that the truck models. F and W are sufficiently dissimilar in design from the model MH that a burdensome production of documents regarding the design minutiae of those earlier models would not have yielded information which would have supported Hofer’s claim that the model MH truck cab was defective.
Hofer’s argument regarding crash-worthiness is not persuasive. Having discovered all possible information regarding the model truck at issue (MH), it was the task of Hofer’s experts to develop and to demonstrate the alleged defects in that model. As discussed above, Hofer had sufficient information about the F and W models to demonstrate to the jury the differences in overall construction. However, no specific allegations supporting the need for further discovery of information were made. For example, discovery may be allowed where a plaintiff alleges that the defendant was on notice of a defect, that an alternative design was feasible and the defendant had knowledge of the same, that a defendant did not eliminate a previously occurring defect in design, or that previous, similar accidents related to the accident at issue had occurred. Hofer’s stated desire to argue that Mack was motivated purely by economics, without regard to safety risks, was completely unsupported and was simply not sufficient to allow an expedition into predecessor models. Hofer relies heavily on Culligan, supra, for support of his arguments. However, the reasoning of the court in Culligan in its discussion of post-manufacturing testing is not applicable to the instant case.
If a party can demonstrate a gross abuse of discretion by the trial court (bearing in mind that in the discovery arena the trial judge’s discretion is particularly
*382
broad),

III.
EVIDENTIARY ISSUES
A. Workers’ Compensation
Hofer complains of three separate instances during trial where Mack raised the issue of collateral sources, specifically workers’ compensation. First, during the cross-examination of Hofer’s witness, Norman Breen (a truck driver), Mack’s counsel questioned Breen on the subject of his pri- or representation by Hofer’s counsel in a workers’ compensation case arising out of a trucking accident. Next, during Mack’s cross-examination of Hofer, Hofer was asked if he knew the cost of a specific medication for which he has a prescription. Hofer replied that he did not, but that he simply called in an order and that it was delivered to him. And finally, Dr. Ralph Brown, an economist and one of Hofer’s experts, was questioned about Hofer’s annual cost of care, reduction to present value, and the statutory discount rate. This elicited a response from Hofer’s own witness that the discount rate was applicable only to workers’ compensation lump sum payments.
Hofer alleges that all three questions were designed to improperly inform the jury of collateral sources available to Hofer, and that the cumulative effect of the three instances was to prejudice the jury, resulting in reversible error. We recognize that, under South Dakota law, the introduction of workers’ compensation into a trial constitutes error.
Stratton v. Sioux Falls Traction System,
B. Cross-examination of Dr. Brown
Dr. Brown was called by Hofer to testify about Hofer’s lost future income (based on claims that Hofer is permanently, totally disabled and completely unemployable), and the reduction of future medical expenses to present value. Hofer maintains that Mack improperly questioned Dr. Brown by delving into the issues of his preliminary calculations of Hofer’s medical expenses (Hofer presented at trial vastly different calculations performed by a different expert), and Dr. Brown’s familiarity with another disabled individual who is employed and productive.
The jury verdict form is crystal clear. The jury found in favor of Mack and did not consider the issue of damages, so this court need not reach the merits of Hofer’s arguments regarding damages. Even in the event of error, Hofer was not prejudiced in any way and the error was harmless.
IV.
PUNITIVE DAMAGES
South Dakota law strictly confines instances in which a party may seek punitive damages. Even before permitting discovery on a punitive damages claim, a court must find, based on “clear and convincing evidence”, that there is a reasonable basis to believe that the defendant has acted in a “willful, wanton or malicious” manner.
Vreugdenhil v. First Bank,
After hearing all evidence presented by Hofer at trial, the district court determined that there was no support for a punitive damages claim, and refused to submit the issue to the jury. Our review of the record indicates that the district court did not abuse its discretion. There is ample evidence that Mack adequately “crash tested” the MH model and a complete absence of evidence that Mack had knowledge of any unreasonable risks or that it acted maliciously or even indifferently in its production of the MH truck cab.
As indicated above, further discussion of the legal precedents on this issue is unwarranted in light of the fact that the jury found no liability and did not reach the issue of damages.
See Fluekey v. Chicago & Northwestern Transportation Company,
V.
JURY INSTRUCTIONS
A. Compliance With Federal Regulations
Counsel for Mack referred during trial to Mack’s compliance with federal safety standards. In response, two of Hofer’s experts opined that such safety standards are minimal standards and that manufacturers have a duty to go beyond the standards and to manufacture the safest possible truck.
Hofer now contends that it was prejudicial error not to submit proposed jury instruction 24, as follows, to the jury.
Compliance with federal motor vehicle safety standards is not, in and of itself, sufficient to exempt a manufacturer from liability.
Standing alone, this is a correct, but not complete, statement of the substantive South Dakota law. Had the court accepted the proposed instruction, Mack would have been entitled to a further instruction stating that the jury may consider Mack’s compliance with standards in determining whether it failed to use reasonable care in connection with the performance of its duties, and was thus negligent.
See Zacher v. Budd Co.,
B. Crashworthiness
Seven of Hofer’s proposed jury instructions were taken nearly verbatim from the language of the landmark case,
Larsen v. General Motors Corp.,
*384
While much ado was initially made about second collision cases, the
Larsen
court itself recognized and stated that its decision was not especially innovative. The court stated, “The duty of reasonable care in design rests in common law negligence that a manufacturer of an article should use reasonable care in the design and manufacture of his product to eliminate any unreasonable risk of foreseeable injury.... [t]he courts since
MacPherson v. Buick Motor Co.,
In this case the court submitted instructions to the jury which clearly set forth Mack’s duty with regard to design, and correctly defined common law negligence. While we agree that this case can technically be described as a crashworthiness case, this does not, a fortiori, mean that Hofer is entitled to the specific jury instruction language of his choice.
[Wjhile a litigant is entitled to have the trial judge advise the jury of his theories and claims...., the actual form of the instructions is within the trial court’s discretion. Counsel cannot, therefore, require that an instruction be rendered in the categorical language that he fancies would be most beneficial to his cause.
Reyes v. Wyeth Laboratories,
We can envision a situation where it would be reversible error not to specifically instruct the jury on the legal principles set forth in
Larsen. See Mitchell v. Volkswagenwerk, AG,
C. Jury Instructions H and 29
Jury Instruction 14 refers to “[t]he conduct of any defendant” and to “any controlling, intervening cause” in its discussion of proximate cause. Hofer maintains that this instruction contains reversible error on the grounds that: 1) the conduct of the defendant is immaterial in a strict liability action, and 2) the jury could have understood “intervening cause” to mean the actions of the driver of the truck.
Hofer finally assigns error to Jury Instruction 29, which states, in essence, that Hofer need not eliminate all other possible explanations of causation in order to prove his theory of causation. Mack posited other possible explanations for Hofer’s injuries and, therefore, Hofer argues that the instruction is “essential” to a fair submission of the case.
*385 We have reviewed the jury instructions as a whole, the evidence presented, and the parties’ legal arguments on appeal, and we determine that the court did not abuse its discretion in its submission of instructions 14 and 29. Again, the issues were fully and fairly presented to the jury. There is no merit to a further, elongated discussion of these particular issues.
VI.
CLOSING ARGUMENT
Hofer argues that Mack’s counsel’s entire closing argument was punctuated by unwarranted denunciations of Hofer’s counsel, designed to inflame the jury against Hofer, his case, and his counsel. While such tactics are certainly questionable, and will constitute reversible error when they are plainly unwarranted and clearly injurious,
Vanskike v. Union Pacific R. Co.,
VII.
For the foregoing reasons, the judgment of the district court is affirmed in all respects.
