U-Joint

U-Joint
I'm putting the final touch on installing a new rear end on my 1969 442 and ran into a snag that you sage mechanics might be able to help me with. The new rear end has a slightly different yoke. The old one is very much typical from my experience. The old one has a machined shoulder on the yoke that prevents the bearing cup from being installed in the wrong position (too far inboard or outboard). The new yoke doesn't have this shoulder so the bearing cup can be clamped pretty much anywhere so centering it is mostly a guess. I really do not want to remove the yoke and replace it with the one that was in the car. Thanks for any input!!!!

Back in the day I remember replacing a U-joint required installing clops that essentially indexed the bearing cup placement. I remember it because it was hard to get the first clip out. But this yoke doesn't have a groove for a clip. The inside surface is smooth- no groove or shoulder to index the U-joint.

Thanks Fun71 for the pix and the suggestion. Both of those yokes could be the same as mine since neither has a shoulder to index the bearing cup. But I don’t see a groove where a clip could be installed. Am I missing something because I’m feeling pretty dumb.

Thanks to all of you guys' advice I thought I was close to finishing up this project but I just ran into another snag. To review, when the shop rebuilt my rear end, they changed the pinion yoke. This new yoke is slightly larger and the old bearing caps are a tad loose under the saddle U-bolts. The new saddle measures 1-1/8" (1.125) whereas the old yoke measured 1-1/16" (1.062). Seems like I should be able to find a Spicer U-joint with a set of two 1-1/16" caps for the driveshaft and a set of 1-1/8" caps for the pinion yoke. They do make this product but one set uses outside snap rings and the other uses inside snap rings. I need both sets of caps to use inside snap rings. I don't mind buying two U-Joints but I don't know if the caps are interchangeable. I'm thinking the trunnions may be different diameters but I can;t find the trunnion diameter listed on the Spicer or Dana website. This has to be a fairly common issue but I can't figure it out. Thanks for any help!!!
