It would be much easier and cost effective to rebuild the toasted transmission, and while you're at it install a Transgo shift kit. Are you sure it is toasted? I recentlly checked one out that wouldn shift at all. Repair estimates were around  $600. I replaced the stripped governor drive gear that costs a meager $ 1.75 in less than hour without removing anything but the cover. and it works just like it always did. I did make him have me install a shift kit as payment for saving his transmission.

yes it had a bad set of planetary gears got another one at a you pull wrecking yard for 50 bucks just had the wrong shaft in it tore it all down and switched the shaft for the books fluid used trany and filter kit it cost about 125 to do the job and I have an extra case to rebuild for when the used one goes out

If the driveshaft is your issue, I have had one made from scratch for my 69 c-10 at a big truck and trailer type place, and it ran me under $200.
