Is it worth the trouble to remove this broken stud? Two other studs broke, and I got them out with vise-grips and cursing, but this one is really rusted into place. I can't get a drill in there because the gas tank is in the way. I could weld a nut on the end, but once again, the gas tank is in the way, and I don't want to flux-core that close to the tank. I'm thinking about just siliconing around it. Yeah, i know....it's really half-assed; but I'm sick of wrenching on this rusted-out POS. Any advice or encouragement?
