I have an 85 C10, short bed, 5600 GVWR, 2WD, 700r4, was originally a 6.2. I bought the Moog 534G u joints for the driveshaft but they wouldn't work. The driveshaft had the original plastic injected rings for the u joints. I would have only been able to get one of the inner snap rings in on the Moog 534G. I'm looking up the parts as if it still had the 6.2 in it. Anyone have a part number for the driveshaft u joints that they used?
