if you buy a name brand easy out, craftsman, napa, american, you are more than likely not going to breack it, get the biggest easy out possible, spary some panther piss, on it lots of it let the piss sit for about an hour or so, try to back it out but not to much pressure, I had the same thing happen, I had to get one of them litte butane torches, the kind for solder, and heat it up a bit no prob then, good luck, its not as bad as it looks
