That's ok if you want to make the old cars run old technology like wide rings. If you want to make things equal you should ban the late model Challengers/Mustangs/Camaros that run traditional stock classes from taking advantage of the older driveline parts they use. In other words, they must run the rear ends they came with. I think the deepest gear in the Challenger rear end is a 3.70. Also require them to run the OE 8 speed automatics. This would be even easier to police than ring size. All you have to do is look under the car. Also the late model cars should be required to run OE type suspension with bolt on parts like the older cars. No weld up link bars and that type of thing. Also no crossbreeding parts, a Camaro has to run a Chev rear end and transmission.
