I FOUND A DIFF IN A SALVAGE YARD FOR 300 BUCKS. I BELEIVE ITS LIKE A 98 OR 99 MODEL SUBURBAN. THEY SAID IT IS A 3.48 POSI. IF THIS INFO IS ALL CORRECT WHAT WILL IT TAKE TO THROW BEHIND MY 85 C10. THE 1 LEGGER JUST DONT DO IT FOR ME.

You'd probably have an easier time just swapping the whole rear end into your '85. The width and everything should be almost exactly the same, and should just drop right in. You'll probably have ot get another speedo gear for your trans though to correspond to the new rear end gear you'll be installing.
