Hi Billy,
I had trouble with one of my anti-roll bar bush screws (with the tiny 10mm AF heads). What you need is
Irwin bolt extractors.
Don't give up on what you're doing. Once the ARB is out of the way you'll be able to use a socket on both lower arm (it's
not a wishbone!) bolts. This will not only make removal easier and safer but will also allow you to tighten them to the specified torque.
