Ok, I'm at work. THe jeep is at home. And the autoparts store is in between. Does anyone know what the P/N would be that I need, since I want ot replace all 4, from the drive shafts.

Or does anyone know how long the same u-joints were used in the Jeeps so that I can have them looked up from a more recent model?

Dont go on this alone but at one time I had a lifted CJ5(1980) drivetrain in my flattie and I used one of the 46 flatties shafts to move it around with, I used the 1980 cj universals and they fit perfect in the 46 2a driveshaft
