As mentioned above. Sell the 8 3/4 while it still is good. It will bring good money to offset your cost in going to a Dana. I used a 3/4 ton truck rear end that I narrowed and put car housing ends on it. Got some 35 spline axles w/ green bearings from Dr. Diff and all is well. Sold my 8 3/4 and when it was all said and done the Dana only cost me a little over $250 to put it in.
