have you gotten this fixed yet? you're talking about the small bolts that go through the CV at the transmission right? not the big one at the end of the axle at the steering knuckle.
the easiest way to remove it is drill the head off, I've got 30 or so axle bolts to spare if you need some.
If you're talking about the big axle bolt, the best is to soak it daily for 3 or 4 days with PB blaster, and then use an impact gun.

no, use a drill bit that is the same size as the head, drill the head off leaving the stud (rest of the bolt) in the trans.
you can get bolt remover like this

the thing is, you can't get the bolt remover on the head because of the CV, so cut it off and take the axle off then remove the stud.

if you cant get it out, then cut it off flush and just make sure the other 7 bolts are good and solid when you put the axle back in. I've raced with an axle that only had 3 of them, it'll be fine.

I've got lots of extras if you need any, just let me know.
