I'm trying to put a rack back on my 1970's Motobecane Mirage, but I have lost the screws that the rack came with. Does anyone know what size and thread screw I need to get?

It's either M5 or M6 bolts. If you've worked on racks/fenders before you can easily tell. Other option is to just try an M5 screw. It will be obviously too small. Typical bolt thread length needed is around 15-20mm.
i haven't worked on them before, but i only need a few screws so i'll just buy both sizes.
thanks for the reply.
