There's a guy who make polyurethane bushings for any vehicle, also to old original parts. I asked him if it would be possible to mold a new rubber to my clutch disc. It is possible, but what is needed to know is that has the original rubber been vulcanized ("glued") to both sides, the center "tri star" part AND to the disc casing, or only to the center part? Any idea? My disc has completely lost the rubber (must have been interesting to drive.) Molding would only be viable, if the parts where it must vulcanize are completely clean. This is only possible to do for the center part. Not really much sense in this project either, but I'd like to see what would be possible options for the future.
