Twisting the axle is not what started this whole issue and isn't a concern. I'll be autocrossing on street tires (albeit 275/50-17 RT-660s). The whole thing started with a bent hub and almost five months of not being able to find any parts to fix the issue (tomj's generous offer was made late in the game and I was already well down this other route, plus another person needed those axles).
Poor strength and durability in side loading.

Copied from a Jeep forum on Set9 installation issues: "If you buy set 9 bearings from Napa or any source other than the 1 piece axle manufacturer, you will end up with bearing retainer rings that are too thick and will rub against the inner seals preventing the axle from being installed full depth. One piece AMC 20 axle kits that use set 9 bearings come with special thickness retainer rings." Hence, the lock rings to make the Set 9 work in an AMC 20 are custom
pieces and the reduced width does not retain the axles as positively axially. Moser used to have instructions on their site for machining the shafts to fit Set9 that originally had the Green ball bearing ... or maybe other way around? Did a quick search and couldn't find it. My suggestion would be to run what you received from Moser with the ball bearing, monitor shafts for movement and be prepared to change bearings frequently. Ultimately, you may need to update housing ends to get a larger tapered roller bearing that is more positively retained, or fit snouts for full-floating ends if serious about autocrossing your car. I'm sure Moser could do a full-floater conversion for your AMC 20, as they offer same for 9", 8.8", GM 12 bolt, etc. Depends how hard you run your car on the track and how sticky are your tires and how well set up the suspension if the ball bearings will give satisfactory life. Hope this helps, RD

That's good info. I'm going to be buying the Moser bearing package via Summit, which includes the rings. The question is whether "as positively" matters in this case, and whether said rings are any different than the ones which come with the ball bearings, in which case there'd be no difference in retention between the two.
It's still there. See "Print for machining seal area to use Timken Set 9 bearings on Moser Engineering One-Piece Jeep axles" at https://www.moserengineering.com/order-forms-instructions/.
It does, thanks!

I have Henrys axles in my 70 AMX. Bought in 1972 for 299.+ extra bearings, retainers and shipping. Stock backing plates + seals hold the axles in.
They recommended tig welding a spot between the retainer and axle which I did. Have had one bearing go bad in 50 yrs and it's a 4sp w/slicks. Of course I welded the tubes and perches. Goodluck, Ron.
