There's no radiator or even core support yet, so I can get right at it. I was thinking that if I had a new bolt, I might be able to get a machine shop to drill right through the center so it would make a nice guide to drill in the very center of the broken bolt. Then I could start the bolt in and drill a pilot hole right where it's supposed to be. That way I could try a reverse direction drill bit or some kind of extractor. Does anyone know the thread size and pitch of the bolt or where I can get that information? Or better yet, does anyone have one? Or any other ideas for getting the broken bolt out?
Thanks a lot,
Scott

Machine shop would be able to get it out better as they most likely would be able to put a jig on it and keep a drill centered to use an EZ out.
