Combo U-Joints
 

Just finishing up a super duty axle swap out of a 99 f 350 into my 96 f250. Having a little bit of a problem finding combo u joints for the new axles. Anyone done this swap before? And anyone know if I can just swap my 10.25 pinion yoke onto the 10.50 to use the same size joint ive already got?

You would most likely need to swap the yoke or buy a yoke to fit that year truck.

How did you deal with the spring pads as they are wider?
Edited...just saw, 10.25, was thinking front
