Not too familiar around this subject, but had a FB400 donor car and had the 400 motor/400TH from this car put in one of my 68 350/Powerglide cars long time ago. How can I be sure they used the 400 car driveshaft in the 350 car as they shafts are different in length, I believe?
I have a drive shaft used on a 68 FB 350HO + 4sp Also have a drive shaft used on a 68 FB 400HO + TH400 I had a 350 /w 2sp PowerGuilde but not sure it's the one I used on 350 HO+4sp
