I used an OFNA Flywheel #OFN18057, Mugen Clutch Shoes #MUGC0707, and Mugen 1.0 Springs #MUGC0708. The stock clutch bell works just fine if you take the time to shim it up, but I'm like eveyone else I think a 16 or 17 tooth bell will be more suited, especially if you put on a stonger more powerfull motor.
