I am not totally sure. I Tried to switch the carriers a few days ago from two rear ends to make a good posi rear end. both rear ends was 12 Bolt. I also changed the pinion and ring gear but then one rear end worked fine with the posi carrier. but the other did not fit so well after. there is to much pressure on the ring gear and pinion even with no shims so you may want to check your carriers before hand and I noticed the area where the ring gears bolts are, there is more tappered and pushes the carrier more the other way and keeps it offset to much. Measurements and eyeballing it may help im not a pro so I am not to sure. also before hand if you really plan on doing this you may want to buy a shim kit.
