Not sure if a 12 bolt is really necessary in a U car. An 8.5" ten bolt with axles, web caps and a spool would probably be 90% as strong as the 12 bolt, and probably a bit lighter besides. Ever pick up a 12 bolt posi unit? If it's a G body, some of the Monte Carlo's and Malibus had them, and the Buick Gran Nationals. They might be getting rare by now,as well. If you get the 12 bolt, assuming it's an A body unit, QA-1 has upper trailing arms made to facilitate the swap pretty easily.Good luck on your project!
