Just got back from the JY.
A T55 Torx fit the best. Definitely not Triple square
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.
