14bff swap question?

[muddawg]

Will the driveline length need to be changed when swapping in a 14bolt from a 12bolt?

14blt is about 3 inchs longer than 10blt so maybe...

I didn't need to change anything except the ujoint at the pinion end of the driveshaft when I installed my 14bff. The stock driveline worked fine.

The reason I ask is because i am going to get a cv shaft made that is going to be hooked up to the 12bolt for now, but when i put the 14bolt in i want to make sure that i can use the same driveline.

i just swapped out my 10 bolt for a 14 and it was the exact same length.

no driveline issues atall, besides the conversion ujoint

X2. My buddy just swapped his 10 bolt out for a 14 bolt in his 84 K5. All he needed was the conversion joint. It's the same for 12 bolts too.

Same with mine. Just put the larger ujoint in and it worked fine.

same here. but i did eventually move the axle back 1.5" with the ORD zero rates so i orderend a driveshaft that was 2" longer and its all good. if your going to keep the same suspension and not move the axle then you will be just dandy...
