Hey all! I am trying to finish a project I've got going. I need some help with my Huret downtube shifter clamp. Does anybody know what bolt I need? An M5 seems the correct size, but doesn't want to thread in more than a couple of threads. Is there a funky thread count on the old French stuff? This is the last piece of the bike. I'm itching to get it done! Pics will be posted if I can get it finished.
