I rounded a bolt on the daggum top left tranny bolt (up against the firewall) I can't beat a 12 point socket on like I normally would. Any suggestions? Afraid to use heat since it is so close to the carb and has oil all over the engine. The only tools I can get to squeeze in there is an open 14mm wrench and vice grips. I've had it soaking in sea foam but am open to suggestions!
