Check out the links section at the top of the page, theres all kinds of places that sell the parts your looking for.
Theres a place in tacoma that a friend told me about that he sends his clutches and stuff to. If I find out any more info Ill let ya know. They can line them with kevlar to, which is supposed to last darn near forever.
Not sure on the drums though. Youd have to bring them in to a shop or your FLAPS and have them tell you whether they can be saved or not. Keep you eye in the bushes driving around! Youll love havin a spare parts truck.
