Early ford trans case: Rear thrust face. Repairable?

[JWL]

I fixed one such case by machining it flat in the worn area and fastening a thick steel washer with c-sink screws thru the rear face into the washer. Made a simple face cutter from 3/8 square tool steel and piloted at both ends of the case with a piece of 3/4" water hardening drill rod. Although I did the machining on a good sized vertical mill it could be done in other ways.
