It wouldn't be worth the expense to buy custom shafts or case. I'm just trying to replace the AMC 20 with something that won't spin a hub or bend a tube. Since neither has happened in almost 28 years, I obviously don't need something super strong.

Just my opinion but that is exactly why you should get a one piece axle kit installed and wheel it for another 28 years. You have lower gears but I haven't broken mine so it's very unlikely you will break your AMC-20 running 31" tires.
May as well go to disk brakes on there while you are at it...

I put in the SSB kit at the same time as Superior one piece axles, only take it apart for a re-lube a couple times a year. Have yet to have any type of problem.
You might think that rear disc aren't worth the cost and trouble. But:
1. Handle mud and muck with out damage and still stop you.
2. Much easier to work on and need work less often.
3. Never need to be adjusted.
4. Clean up with a pressure wash.
5. Allow the axle to be removed without opening the brake lines.
If you are an eBay junkie it might be possible to find a SSB Kit for less than half price. I did.
TSM will sell a complete kit or just the brackets. Get lucky at the salvage yard finding an old Caddie with new brakes and you have a low cost setup.
