Eric: I believe I have what you are looking for. If I recall, these bolts thread directly into the crank arm or chainring, and don't use a hollow nut. In any case I just have the three bolts. They are 9mm, unmarked, chromed and take a 4mm allen wrench. I found them in my small parts drawer left over from my bike wrenching days in the late 70's. Seeing how these may be the last available set in the civilized world, they will cost you dearly. Send me your address and they are yours...

Hi All,
Yes, 9mm in diameter, not the normal 10mm. I have a '78 Raleigh Competition GS. The crank is Campy but only has 3 arms, might be part of the nuovo gran sport group (?). I've looked on ebay, shopped online, brick & mortar bike shops - no luck. Can anyone help? It would be much appreciated!
