Ok, gave just about everything I know a shot this morning. I punded the shit out of this with a 5lb mini sledge, and just about everything else, including my fists, when I got angry enough. I can not get this sucker to move, even 1 mm. They back, threaded part, of the the bolt is just kind of mushrooms out, and will no doubt eventually receed back to the frame. I am fresh out of ideas, and again, any help would be greatly appreciated. This bike was neglected by it's previous owner, and the greases fittings were rather dry, I'm guessing that's what caused this. I included a pic below, the threaded portion is circled in green, and the head in blue. Thanks again!
