Hey Guys, multiple questions.... will the original bell housing, casting # 3733365 fit a big block or should I go with what I have an aluminum # 3899621, trying to make this fit easily and modify as I go,... if I go with the aluminum bell housing, the installation has more questions...first.. the transmission mount, ..go with the aftermarket bolt on unit? who do you recommend?.. also what ,if any is the degrees need to send the tail shaft properly to the rear end? so the pinion angle is correct,before I bolt or weld the tranny mount in place ..second the clutch linkage.....build my own, or is there an aftermarket set-up readily available? or can I modify the original set up to fit the 55 chev? Thanks Mike
