I finally tracked down an 8.5 out of a 72 skylark locally. LL B295 2 is stamped on it. It and the ring gear says it's a 2.73. I will be replacing the 8.2 in my 70. I currently have 2.56 open rear with 28 inch tall tires and a 4 speed m20. Its a highway cruiser and a Dog off the line. Hopefully the 8.5 will help me light the tires up and take off harder. I am going with the Yukon Duragrip 28 spline carrier and the Yukon 3.42 Gears. Will this Rebuild kit be all that is needed to replace the bearings? I have a shop that can rebuild it for $450 with me providing the parts. My plan was to remove the rear and install the 8.5 after it was built. I should be able to do this with jack stands and a regualar big 3 ton jack right? Any tips? I will also have the driveshaft shortened 1inch if I remember correctly. Can't wait to see how much of a difference it makes.
