1963 differential
I have a 1963 open rear dated (D 8 3) and want to find out if pinion gear thrust washers were used in these rears. I purchased 3843266 thrust washers for 64-65 open rear but after rolling them in, the spiders will not turn.
Old GM parts book does not indicate part # for 63 and earlier pinion thrust washers and I remember overhauling this rear years ago there were no thrust washers there, I was first in there.
I also installed a NOS 3977298 pinion shaft and two NOS 9789002 side gear washers. I installed the side yokes and I bet there is not .005 end play in these stub axles. I will post a pic showing wear on the pin compared to the new pin, well worth the couple dollars for a good rebuild. The pin must be softer than the side axles.
Thanks for all input..
