M S:
Possible repairs for your shaft would be having the thread area welded up, turned, and threaded. Also, a new one could be fabricated using the old one as a sample.
I have another solution which you may be interested in. I have a NOS shaft in what's left of the original Ford box, with the three large dished washers, two lock washers, and two nuts. It was originally a kit Ford #B4A-3047-B, but the rubber bushings are not there. $100 + shipping from East Central Indiana.
