Broken anti sway bar mount bolts
Good morning Jeepers, here's my dilemma: PO removed the anti-sway bar and broke one bolt off on each side in the captured nut for the mount.
I want to reinstall the sway bar, so I used penetrating oil for about two weeks and heated/cooled several times w/small propane torch and penetrating oil. I was optimistic that the left hand drill would spin out the broken bolt shafts. Unfortunately, it didn't. The first bolt I successfully drilled all the way through w/a small bit. The second one spun and the bit suddenly broke.
At first I thought I would have to weld the mount to the at the forward end to compensate for the missing bolt, but I thought I'd check w/the Forum to see if I can still remove the spinning and damaged nut plate. If so, how please? BTW, I still haven't extracted the bolt through which I successfully drilled w/the small bit. (original plan was to start small and work up toward 7/16 size, hopefully, without damaging the nut plate)
Thanks for your help,
