I've used Simplex Retrofriction brazon shift levers, which are made for standard Campy brazeon bosses, on the clamps from the cheap plastic Simplex Prestige shifters like found on a UO-8. The more expensive Simplex clamps don't work but the Prestige clamps do. The Prestige clamps are actually pretty nice, although the levers themselves are crap.
Not sure about the thread on the fixing bolts though. I'll try a Campy fixing bolt on a Prestige clamp this evening and let you know if it works.
