About to start the rebuild and upgrade of the 8.5 10 bolt in my 79 Z. Here is what I picked up. 30 spline 8.5 detroit trutrac AAM 3.42 r&p. Appear to be 2 cut Moser 30 spline axles Yukon 8.5HD install kit Includes all new Timken bearings. New Timken axle bearings and seals Moser 1350 pinion yoke The original rear was a 3.42 open. 1st question of many I assume, I disassembled the original pinion bearing and it had a 0.038” shim.
