The "hanging bolt" or "pivot bolt" assembly which held the rear derailleur to the frame of my son's old mountain bike disassembled while he was riding it and vanished. Is it possible to find generic replacement parts or does it need a whole new derailleur (it's an old Suntour Accushift \alpha-2000)? What's the cheapest way to get this bike running at this point?
