the truck pinion shaft is smaller than the car 12 bolt..(what was g.m. thinking) but you might be better off just fixing the 10 bolt 8.5" rear
I thought it was the other way around and the truck 12 bolt pinion was bigger than the car 12 , could be wrong though.
I know there is nothing wrong with the 10 bolt in my truck , but just my personal preference and I think it would add a little value to the truck in going with the 12 bolt.
