Looks like the corvettes and the pantera ran starting in the 1973 season. Arguable if 1973 qualifies an early 70s. I did find the tempest in (I think) the 1972 season interesting. I didn't know a tempest ran trans am. I would have to look again to be sure.
For our purposes I think early 70s would end at 1972.
At any rate I agree that the rules are fine as they are written. If they started changing them I think people would leave the class.
