Does anybody know if the driveshaft length varies between a car that is set up with a super T 10 and replacing it with an M21?
Also, I desperately need a set of 74 firebird core support bushings. Any referrence?

Slobrd,

If I recall correctly, the M21 & S-T10 have the same overall length (+ or - a 1/2" or so). The only problem would be output shaft incompatibilities. Early muncies and t-10's had a small output shaft, while the later muncies and S-T10's had the turbo 400 large style output shaft.

Good Luck
