Yes, 74/75, maybe a 73 too. They are not offered in the aftermarket. If you need a new one, some of the RD models as well as TX750 also ran this same style. Or hit up DogBunny. I think I've seen some of his listed on Ebay. Rubber kits are available to rebuild them though. I got my seals through HVC Cycle. It is a tricky setup to get reinstalled properly. I did a write up when I rebuilt mine. Let me see if i can find it in the archives.
