So the little bolt with the nut that goes through the rear coaster brake arm I think the threads on the bolt are stripped. The little nut spins freely but won't come off. I'd rather not have to resort to using my Dremel on it or having to drill through it. I even tried holding a torch to it to try to heat up the nut but it didn't help. What else could I try to get that bolt out without having to Dremel or drill it? Any help will be appreciated.
