Yikes not the best way to ask/get help
the "weld a bolt after it shears off" is the best fix i know of
(worked on manifold studs,lost locking wheel nuts,done this lots of other places)
i tried sand blasting of the bolt clean at the bottom didn't help
Snapped all my torx
It was suggested in another thread to grind the head square to fit a socket...
to bad your past that point
If your choice is to drill it out you can use large size proper grade bolts and large washers to repair this problem

Really the only other option you have is to lower the gas tank and grind off the welded nut, then replace with a bolt of the proper hardness. I had to do this on one of my trucks, but luckily it was the side without the gas tank.

Drill them dead center. Start small like 1/8 and work your way up to about a 5/16 bit. The threads will practically fall out. I do it all the time. Drill a little smaller than the bolt size.
