or anyone else who may have sugestion have got my 79 frame under my 64 f100 in mock up stage heres my question i am changing the rearend back to the one out of the 64 orginally in order to tuck my 50s under the wheel wells in order to do this i had to move spring saddles the ride height is going to be orginal i am wondering about what degree to start with i was thinking about 2 to three degrees up and then adjustit with shims from there once motor trans and drive shaft are in what do you think
tks paul
Not sure I completely understand the question, so here's a shot in the dark. We are talking about pinion angle I assume.
If the ride height is not changing, then you want to duplicate the pinion angle of the '78 rear end. It's likely the '64 is probably close to that of the '78, but go with the angle the '78 had.
tks pro stock but heres the thing i went to answer the pnone and a guy that works for me cut off the saddles and ground off all the welds thinking he was helping( on both axles} god only knows why ??? you know its nice to have help you didnt ask for huh!!!so where to start is the problem i have shims to change the angle but dont want to have to use more then 1 or 2 on the semi truck we work on the suggested driveshaft angle is 5to six degrees from pinion yolk to trans or carrier beering but not sure on a pick up i guess i could just tack the spring pads and wait till i get the drivetrain in place and then cut the welds and adjust the pinion anglebut i didnt want to cut or weld on it once tne chassis was painted tks for your help paul
That sucks.
From what I understand(and this be completely wrong), you want the pinion centerline to be parrallel with the tranny output shaft centerline. Erring toward having the pinion nose low so as to compensate for some axle wrap on acceleration is desired. How much? Dunno, I guess that's where the shims come into play.
