1) get a dremel like tool and cut 2 notches into the bolt so you can use a flat head screw driver on it (use something to get good leverage on it)
2) find a screw extractor for a power drill, it has a reverse thread so when you push it into the stripped area it will bind to the metal, obviously use a low rpm/high torque setting on the drill
