So you're saying the bolts that hold the ring gear to the carrier are sheared off?

You're not giving us much for details. Look up a diagram of the parts, and tell us exactly what is going on.

If you have to ask what the part names are for the pieces inside a differential, you have zero business attempting to put a new carrier in and setting up gears in one.

I'm not being an ass, I'm dead serious. This is where you pay someone to put it back together. It requires some tools you probably don't have and more skill than the novice mechanic has.

I was asking because I know someone that has a 70HD for sale. Obviously I'll need to do more research but I wasn't planning on doing this myself. I'm just trying to determine if it's worth buying.

If it has the right carrier break (4.56 and up) and gear set, and the price is cheaper than the parts new, by all means snag it and have someone transfer the internals.
