Anyone have the Differential bearing part # and where they get them. Dealer? Also it seems like the input shaft bearing is a little loose. It doesn't look bad but the end play seems a bit much. I need to get a dial indicator and measure it to find out where it is but I'd guess 8-10 thou. What should it be? It would probably be a good idea to replace it anyway so does anyone have the PN for that bearing also? I'm also installing a OBX and read somewhere I should pick up a set of shims to set the preload but I can't find the post with the part #'s.
