So the A10 fits in the Camaro but not in the Corvette. And the M7 fits in the Corvette and not the Camaro? I think I'd need some more evidence to be convinced.
I was comparing pictures of the TR-6060 and the TR-6070. The center sections look nearly identical.

Obviously the TR-6070 would need to borrow the bell housing and tail housing from the TR-6060 to make it work in the Camaro, but is there some other problem?
