Found these today while looking for something else. I THINK, but make no promises, that these are Campy toe clip bolts( 8mm head, thread into the twisted hunk of metal that was once a Campy pedal)
They are of no use to me. Even if I had a pair of functional Campy pedals, they are too short for me. I have to space the clips out a bit because of a long ago foot injury.
They are yours for postage.
