Is there anyone who has had a 29 flywheel repaired. The ring gear is badly damaged and needs to be repaired. Does anyone know where I might find a ring gear or have one made that could be installed on the flywheel. There is no replaceable ring gear on the 29 flywheel. The gear is cut in the perimeter of the flywheel and the flywheel would have to be machined to accept a later model ring gear. Any help will be greatly appreciated.
