At least all the teeth are still there.... previous owner probably didn't like to double clutch........

You could try to dress up the meshing end of the teeth to be round like the oiginal configuration BUT you will be removing more metal.....

Why don't you ask around for a new or almost new or better than yours on the Forum....... the hard parts to find on a CMP tranny is a good housing that has both the bolting ears still in one piece... and the proverbial rear cover which usually suffers from what we call a "Mooney job" after the early article on why back covers get broken....... gears are usually still very good..
Early tranny rear covers were white metal....very soft and fragile..... usually recognized by the machined speedo cable port and fitted with a threaded plug. The more sturdy model is the later ones cast of iron and the speedo port is blank and not machined at all.

Your biggest problem will be the shipping cost for the shaft...... ask around on the West coast .

If you really get stuck I think we have some in the barn.......

How are the tranny bearings...?? they are available and now is the time to replace them if at all necessary....... remember all the metal missing on the gear teeth must have been floating around for some time...
