    I have a 79 Suburban C-10 with a trashed out 12-bolt rear end. I need to know if I can use a 1984 10-bolt in this truck while retaining my larger Suburban brakes and the same driveshaft.

    just my personal opinon jim, i would stay away from the 10 bolt. I myself have trashed a couple of those when i had my 2WD 81, (I'm also 24 with a lead foot, though) If you can, try and find another 12 bolt, or even a 14. not sure that you can use the brakes from the 12 on the 10.....maybe wyldman knows....:(

    I have a 1984 K10, and trashed the rearend in it a couple years ago. It was a 12 bolt, which was not original, and I put a 10 bolt back under it, which was the original size for that 1/2 ton pickup. My brakes hooked back up just fine. But I too would stray from the 10 bolt if possible. I used it only because it was the only 3.08 ratio I could find.

    Yes,it will pretty much all bolt up no problem.The 10 bolt isn't all that weak,and should do fine as long as it's not abused.

    Thanks for the info. I already have the 10-bolt, & I doubt my stock 350 automatic will hurt it. Time to get dirty I guess.
