dude, it sucks but i wouldnt stress too much about it. id talk to some of your buddies about it because tools for situations like yours arent a commonly used thing so theyll most likely be more than willing to lend it. i think they make suttin called an easy out to pull broken bolts, not positive though. what im thinking of you drill a hole into whats left of the bolt, then theres like a reverse threaded screw that actually loosens the remains of the bolt as you tighten the screw. ask around an lemme know...
