Ok, here's an update. It took about a month of looking on Craigslist but I was able to find a replacement axle assembly. It came from a 63 Fintail so all of my drum brake parts swap over, ratio is stamped D 3/9, which I guess is 3,96? Owner claimed it's been gone through, we'll find out, paid $250 delivered to my door.
My mechanic offered to let me use his shop and tools, and he was a big help when it came time to remove the compensating spring, we used his plasma cutter to fashion the removal plate per Wagas's instructions. Also, his transmission jack was excellent for supporting and dropping the whole thing down. I'm keeping my springs, pads and strut, most everything else looks like a direct swap. This axle does have studs instead of threaded holes but it doesn't bother me much.
Ironically, I was able to drive the car the 7 blocks from my shop to his, my camber specific functionality problem seems to be absent for now. If I could have removed that right side shaft I think I could have fixed my problem, but after a few straight days of trying to get it out I decided my time is worth more than the money to replace it.
Here's a couple of pics from today (Friday), on Monday we'll install the replacement, pictured below. Thanks to all of the great information on this forum I think I understand the approach but feel free to let me know if I'm headed toward certain disaster
