There are socket type bolt removal tools. However there is not that much exposed stud to grip.

Best way is to heat the stud until red with a oxy/acetylene torch. When the stud has cooled back to normal color, apply wax around the thread area to try to draw it into the hole.

If you can get the stud to rotate any amount, start using a penetrating fluid. An autotmatic trans fluid and acetone mix works well. Work the stud one way and another to loosen it up.

If no oxy torch try a hand propane torch to heat the stud and draw in the fluid.

If no torch try a small pipe wrench.

Vice grips might work be tend to just to round the stud as the teeth slip, making the stud even more difficult to grip.

Thank you for your reply it really helps a lot, but what do you mean by "draw it into the hole" and I have a few different pairs of vice grips, a one foot pipe wrench, I may have a 6 inch one. Would PB Blaster work?

Wick into the thread area around the stud.

PB blaster also OK but if heating don't catch it on fire.

The issue with vice grips is the teeth may not be sharp enough to really grip the stud. Need to get wrench super tight or it will slip.

I would apply the heat to the housing, not to the stud. Remove as much of the surrounding stuff to gain a clear access to the stud and housing. If there is room, clamp on a vice grip plier and apply force while heating the housing. Don't burn yourself.
