3speed to C4 - HELP NEEDED
Switching from a 3 speed manual trans to a C4 in my 67 fairlane. Pulled the 3 speed today, I've got a 1977 C4 that has been done over recently and I'm switching out the motor to a 351w from a 1974 torino.
Heard a nasty rumor that I could use the same crossmember from the 3 speed for the C4, I tend to think that was wishful thinking after sitting the 2 transmissions next to each other. Also I need to know if the drive shaft length needs to change, and if I need to get another universal joint, I think so b/c I read on one of the other forums that the later model C4 transmissions have a different spline count. Any info to confirm or contradict would be extremely helpful.
