    I blew my 10 bolt rear end out of my 84. Cracked the carrier all of the way around it. The thing is a buddy of mine gave me a carrier out of a ten bolt so he says, it came from a 77 Chev Pickup. It's stamped with GM44 and my 10 bolt is stamped with GM 87. Are these two different carriers or does this just indicate different years or something like that? The distance between the right side and the ring lip looks a little bit different but I don't know. Is this a different carrier? Will it work?

    I'd say no, it won't fit, especially if you can see a distance. You can shim the carriers, but problems I have seen trying to swap them from one axle to another (like you are trying to do, not 10 bolt to 10 bolt) is that you have to shim it so much, you can't get the c-clip back on. As well, if you don't have the same ratio carrier (say you had 3.08's, this one is 3.73) the gears themselves likely won't interchange. Don't recall if anyone has noticed or not on the truck 10 bolts, but the 80's cars got two different size carriers, and 3.08 carriers did not interchange with 3.42/3.73 carriers.
