I just bought a 1965 complete 8 3/4 differential for my 63 SF. I want to change the pinion seal before I put it in the car. Is this as simple as pulling the U-Joint yoke, replacing the seal and replacing the yoke? I am concerned that pulling the yoke will change the pinion / ring gear setup. Any help would be appreciated.
