Hello all, I have a 68 chevelle that came to me with a BOP 12 bolt posi. I know there is a difference in the chevy 12 bolt uppers as one of the two is clearanced and reinforced. I would like to know if there are any other differences, I swear I read that in 68 they had two different sets, or they were just plain different than other years. I need to replace mine and would like to use the chevy 12 bolt ones so that when I do roast this rear I will be able to bolt in a chevy 12 bolt. Can I just buy some from any other year? Or is there something I havent got right here?
Thx Bill

ok should I consider 33 guys and no answers as an indication that there is no differences??
