I just bought a 8.5 rear this weekend and its a non- posi unit so I want to put a new dif. In it and a few other parts. I was wondering what posi unit everyone uses for there rear end? I will need to put c-clip eliminators on it too but Moser sells them in two different axle seat diameters(1.533 or 1.398) for a GM 8.5 rear end and I didn't know which one to get. If anyone can give me some feedback about these thing it would be much appreciated.
