Some CR motor parts, some KX plastic, Husky bearings, assorted other parts. Personally, I use Braking brake pads and most of the rest of the parts I use genuine TM parts. The best thing to do if you're going to get cross-over parts is have the parts in hand when you go to the shop, and then write down the numbers for the next time. I don't know where you're located, but Town & Country Cycles in NJ has a large selection of parts and is accustomed to shipping parts to wherever. Motowest in CA ihas a large selection as well.
