Rear main seal, slave cylinder. Also, when I was searching for the flywheel, I was recommended to get a rps combo with 6 puck disc. The 6 puck disc sucks for street driving. If you want a street able clutch, just go with trd twin plate. It is an extra 500 but good investment imo. Also, if you have a v160, you will hear a rattling notice at idle with the light flywheel. I would contact Dusty at mvp, and he will explain you the applications and any parts you may need.
