I've got an old Peugeot that I'm trying to put new shifters on, but the threads of the braze-ons are M5x1.0 instead of M5x0.8. I can't seem to get any screws with this thread pitch, so what's my best option?
If I tap, can I tap to M5x0.8, or do I have to go to M6? I don't have any experience with tapping threads. Thanks for any advice.
