4\" lift rear drive shaft to long So I was all ready to bolt my rear drive shaft in yesterday and I didnt really think that the drive shaft would be to long if any thing I thought it would be to short. I did put the shackle flip on and repaced my eaton rear with a 14bff. I think that the 14ff 's yoke sticks out a lot more then the Eaton's, so i have to take it down and get 1" removed from the rear drive shaft and the front needs 1/2" add. Why cant these things just work the first time. Wells shes almost on the road All I have to do is the drive shafts, finish brake conversions, put the bed back on.
