Well - I've done the Pure Stock drags for quite a few years now.
The rules for the main one (at Mid-Michigan Motorplex in September) merely state:
The rear axle must be of the same manufacturer as the car. Any gear ratio is allowed.
Note they do not specify any year range.

I'm not racing the car in question - at least not anytime soon!
The thought now is that I would like to collect a 4.11 gearset for the existing rear.
