1962 C40 wheel bearings

[Steve67L-79]

I picked up a 62 C40 and am going through regular maintenance items. I have the front wheels apart and am packing and putting in new seals, next to the rear end with seals and wheel cylinders. My problem is that one of the inner wheel bearings is bad and I am having no luck finding a replacement. Does anybody have an existing part number to replace the original, or part numbers to go to the newer roller bearing wheel bearings?
