So I am changing the bolt pattern on my 63 rear axle. When I pulled the spider gears out of my open diff. there were no cupped washers? I wouldn't have even noticed if I hadn't watched a few Utube videos showing them being put in. I have a receipt of the rearend being completely rebuilt around 4000 miles ago. I have put about three thousand miles on the truck, no noise and the spider gears look fine? Any Ideas? Could they have NOT come with them in 63?
Thanks
