All I had was a cheapie O'Reily torx bit which rounded out the
bolt head & socket. So I should look for a "spine drive" bit? What size 12M?
Should have used some kroil first, too
Still not sure if those axles will go on my diff so I may just pass on them.

highly doubt its a T55 and its a pretty much given thats the reason it stripped out the bolt head.
I have seen this issue on toyota head bolts, they are bi hex drive which look 90% the same as XZN - the XZN tool also fits - the problem comes around applying torque to them. An XZN driver in a bi hex fastener head will only contact the edges of the serrations which will round/strip/give up and then you would have another headache at hand.
I have successfully removed such bolts with the right driver bit, some cleaning with a wire brush and some valve grinding emery paste to give added friction.
