Hi everyone. I'm new here and got a question about rear ends.
I have a 85 gmc sierra classic 2 wheel drive. It has a 10 bolt rear end. I purchased a 12 bolt rear end to replace it. I have a bunch of casting numbers from the 12 bolt and just trying to figure it out what it is from. Why I'm asking is because I'm buying a locker of it and want to purchase the correct one. Any help will be great.

Inside on the gears it says 10:34 gm
These are all I found so far. If there is more please let me know
Thanks
Adam
