HELP!!

My 2 rear seat bolts are broken-off flush (or slightly below) the surface of the floor of my already-painted truck - so I can’t use heat to get them out.

I successfully drilled through one of them but because it was broken off below the surface the hole isn’t exactly centered - still haven't figured out how to get the remainder out without destroying the threaded hole? I may have to just open it up to 3/8” and tap it for a larger bolt.

BUT the big problem is I broke off a drill bit IN one broken off bolt! DOH! DOH! DOH!

Online I found Denlors Tools offers something they call a “Rescue Bit” but they’re pricey as hell. $64.98 plus $5 shipping on Amazon for one 1/4” bit. Yikes. Anyone have a cheaper or better suggestion that won’t bugger up my new paint...much?!
