Hello NID in Fla
Welcome to The forum. All you need to build a dry clutch is a factory a lot of $$$ and a degree in engineering. Or a centrifical clutch and a way to adapt it. Western Auto has them. Also PeP Boys, I think? Why not take a look @ Dax & Spookytooth motors. Also Ebay but their like a box of choclates, You never know what you will get.
