It's one of the bolts that hold in the cab gas tank. Head came off when I was removing the tank.
I tried an easy out but I botched the job! Oh well, it was my first time.
I'm taking a welding class next semester and I think I'll just hold off on that bolt. It isn't essential and I can just remove the seat and gas tank and get it out later. My dad is a master welder but he's too elderly for that sort of thing now. A good friend is a welder also but I don't have 220 volts in my garage.
So I may just wait till next summer.
Oh yes, my dad agrees that I can just drill it out, after I smash what's left of the extractor I broke off! LOL
