Hello All. I need the following for a Campag.steel Gran Sport rear derailleur. 1. PN. 99, Controlling bolt. The dohicky that acts as a stop for the jocky wheel cage. 2. PN. 169, Roller with cones and balls. The jockey wheel (steel). 3. PN. 80, Fixing plate. The thing that allows you to mount a rear derailleur to a dropout that doesnt have an intergal hangar. New or used is ok. Thanks!
