Hey gang, Looking for some part information on the oil seal gasket that goes between the rear hub's outer edge and the 5-bolt hub cover on my 1954 series 4100 1 1/2 ton. It has a splined profile on the inside edge to match the inner profile of the hub that the axel teeth mesh into. Approximate size is 4.72" OD / 3.30" ID. I took the measurements off my hub, not the actual old gasket itself. I've attached pictures of the old gasket and the hub.
I need an original part number to use for reference if possible, or maybe someone already knows a good replacement?
I've been able to find quite a bit of part information online for this truck, but this one is hitting a dead end.
