I have a gov bomb that exploded and was wondering what came in the 10 bolts in 88 blazers without the G80 code. Was it just an open carrier or what? Did it have a locker of some sort? The reason I ask is because I've been looking all over ebay for a replacement and I see 2 types of cases for stock 28 spline 8.5" carriers. My case has the 04-6 stamped on it. I'm wondering if the other type of case would fit in the housing with my 3.08 gears and not need a shim of some sort. Also I see the 8.5 car cases with the posi and that little S clip inside, would that work in my 10 bolt aswell? Very confused as you can tell so I really appreciate all the help you guys can give me.
