In regard to Larry's point, I know that the Campy drop center bolt worked when used to replace the center bolt of an original Dura Ace sidepull brake (Idid this back in the 70's), so I'd guess an old Dura Ace center bolt would probably work with Campy calipers, though I haven't tried it. There's probably a fair chance a Superbe center bolt would work on Campy also, since Superbe was a very close Campy clone. Not that any one of these is necessarily any easier to find than Campy bolts, but at least you have more chances at something that will work.
