Gah! my B-pipe screws broke!

Location
Las Vegas
The guy who had the ski before me didnt put any anti-seize on the screws and well...now they are broke.

The Top one is alright but the middle one broke completely flush just removing the locking nut, bottom one might be able to get removed with heat and some vice grips.

How the hell do I get that middle one out? Drilling out a small SS bolt seems like a pretty hard task without a mill or something.
