Early ford trans case: Rear thrust face. Repairable?

[bobH]

I've only crossed this bridge once, and it was back in the 60's. (So, I'm dated.)
At the time, we had a cast iron repair place nearby. I took the case to them, and they applied braze material to the severely worn area. Looking back, I know I could have done this myself.
Anyway, they put on extra material, which needed to be machined down for proper cluster end-clearance. I was VERY lucky to work at a place that had a great machine shop. And, I went to the tool crib and borrowed a back-side spot facer. The cutter was the same diameter as the thrust washer that needed to rest there. And, the shaft was the proper diameter to fit the countershaft hole. So, I simply did a back-side spot face, using my drill press. After reading all the above posts, I can't believe how lucky I was to be able to do what I did. It worked perfect.
And, by the way, I'm still in contact with the person that owns the vehicle with that transmission. It's been 50 years, and that transmission is still working fine.
