Finally started setting up the differential and gears. I Ended up not working on it the last two weeks because I was missing the 1350 input yoke. Funny I took for granted that the local drive-train shops would have it in stock due to my lack of experience. I had to order it costing me a weekend. As mentioned above I also misplaced the pinon lock nut. I called GM and they said they had one. Unfortunately when I got home it was 7/8-14 rather than the 7/8-16 thread that is needed. Gosh I have forgotten all the little things that can go wrong with a simple axle build-up. I need to start planning a little better. I will post up some more pictures tomorrow. If I can't find the locknut tomorrow it will be shimmed and the pattern set, but I will have to stop there.
