I've talked to Carmen about this off line.
I think Brian Henderson,(No not the SCW BKH),looked at this car recently.
I will send you his contact info.Carmen.

Begining in 1970,the only 4 speed Manual Trans you could get behind the 1970 Chevelle Super Sport new 454 LS-5 or LS-6 engine was the M-22 rock crusher.
Less than 2,763 1970 Chevelle-Elcamino-Monte Carlo LS-5's received the M-22 from the factory.
The SS 396 got either an M-20,or M-21.
