Did you use an easy out to get the broken stud removed? I've had some success with that method. Drilling out a broken stud sounds difficult. In the old days, we had a "electro-discharge machine" or ECM that would "spark" away the metal. We used it to remove broken taps. Made the job easier.
I did not use a easy out, just drilled out a hole slightly bigger than the stud and re threaded it, I only drilled in probably about 6/16ths or less of a inch, so I never went in far, just far enough that the new bolt i screwed in would be in there snug.
