I'm working on a 1941 GMC CCKW 352 closed cab truck that has had to many people with chisels working on it. The rear axle outer spindle nuts have been really abused. The axle housings are the bolt together (split?) type. I would like to replace the outer nuts so the seals have a fighting chance, as the nut also acts as the sealing surface for the seal. The nut measures 2 3/4 across the flats and the sealing part is 2 1/2 inch. I really don't want to machine these from scratch. Does anyone know if they can be bought?
