Thanks for the reply. The universals that are on my car don't have C-clips. There is a "tang" on the pinion yoke that holds the universal in the yoke and then U bolts hold it in place. I've got an idea that because of the short 8 1/2" driveshaft the pinion angle may be off a little. (Down) I just can't figure out why only the two cups that are in the pinion yoke wear but the other two show no wear at all...

Regards,
