Cab Bushings Gone Horribly Wrong!

[jermasaurus]

I went outside to change my front two cab bushings, sprayed them with some rust penetrant, and started to go.

I went to break the drivers front loose and the bolt just twisted in half right where it goes into the body. It is way too hot out to mess with this and be pissed at the same time so I figured I would come inside for some suggestions.

Anyone know what to do? The stuck part is not really sticking out far enough to grab it. Should I attempt to drill it out and rethread it? I wish I had a picture, but I don't. Any advice?
