Question 90 burb Broken power steering/alternator mount bolt

Broke an ear off of the old mount which made the alternator pulley blow up and my belt fly out like an eel in hot water. Went to put the new mount in and was tightening the top nut and the bolt just twisted right off... Anyone have ideas for getting that out? I'm guessing I just drill it and thread the hole again?

Thanks!

Oops, guess I don't have the marked up picture. It's the top left bolt under the valve cover.

Here's what's left... Not sure how long they are.

I would try an ez-out or LH drill bit before I drilled/tapped it larger. Don't forget to soak it good with penetrating oil the day before.

^yup, I'd add put a torch to it and heat it up, it probably "rust-welded" in there.
