well, tried the square/drill a little/hammer it in/ back it out whith a wrench type of bolt extractor, it broke off in the bolt hole that I drilled. nothing I had was drilling thru that piece of extractor, as it was too hard( not hard enough for the bolt to come out though) he he he/. so anyeway, after becoming way too pissed to be coherent, I hit it with the map gas for a good minute. put the pipe wrench on it, had the wife hold the forks still and pulled til my eyes crossed. and CRACK it popped loose like it was concreted in place. did a little happy dance after that crap...
well add that one to your last resorts....and don't forget the happy dance!
