I have a pretty comprehensive arsenal of tools to combat this issue much like Killer Bee posted... But, when they won't work, welding a nut to the broken bolt with a MIG gun works like a charm. I had to do the same thing two weeks ago trying to get a 5/16" bolt out of the core support of my 1965 Chevy Bel Air... I broke the bolt off flush with the threaded insert in the core support, so I drilled a hole all the way through the bolt, then got a little too aggressive with it and snapped of an Irwin spiral flute extractor in the broken bolt. I cussed a bit, took a sip of Miller Lite then welded a 5/16" nut to the broken bolt with the welder turned up a bit. I was actually shocked out how easy the bolt came out after welding that nut on it. I guess all the P'Blaster I had previously soaked it with and then the heat from the weld helped out too?
