"Hi, I'm Doug. I work with 20 great guys in St. Louis at Doug Jenkins Custom Hot Rods, and we're going to do some work for you today on Expert village. So Mark gets the vise grips adjusted just right. If you've got enough of a nub there you can grind a flat spot on it so you have a real good purchase with the vise grips. And it's going to be the same drill on this side. Be real patient, heat up both sides, get around everything you can to get the thing as warm as you can and the housing will expand there when it gets hot and with any luck it will let go of what's left of that broken bolt. He's probably been heating it now for 5 or 8 minutes. You just want to let the heat sink in there. If you get the bolt to move, turn it back and forth. Don't take a chance on breaking it off flush. It looks like it's going to come out this time."
