Well I'd like to make it a driver - a car that could be driven on the road. To do this, I know I need a rear with gears something like a 3:55 in place of the existing granny rear. I'd like to keep it simple & think I'll go for the 66-77 Saginaw 3 speed. I am not opposed to tossing the torque tube rear. What I don't want to do is get involved in cutting up the rear crossmember. I was reading my Chevy shop manual & a number of improvements were made in 1954 to the clutch assembly (also the 3 speed tranny). It sounds like the 54 clutch would be a good choice. I looked at an on-line version of the Chevy Master Parts Book & it appears to me that the flywheel for the 54 car has a different part number than the earlier models. I assume this was done to utilize the new clutch design (maybe for tranny also?). Is anyone familiar with this aspect of the 54?
