Hi, Dixie Gunsmithing,
I would have annealed and re-tempered that bolt had it been thicker, but it looked like someone had thinned it down and I was reluctant to try to re-work it. The timing was OK except that the bolt kept slipping sideways off the rebound lever cam even though the cam looked good. So I cut two coils off a coil spring and inserted them behind the end of the bolt. So far, it has held up fine and the gentleman is happy. I didn't guarantee it would hold and if it doesn't, I will try to get a new bolt.
