I also purchased and installed a set of factory 4-speed pedals from Frank:
Included with the pedals was a complete (and I mean complete) mechanical clutch linkage, but the z-bar interferes with my Summit mini-starter so I'm going to be using a Keisler hydraulic clutch actuator (as soon as it shows up anyway).
The bellhousing is a McLeod SFI approved unit. It weighs 44lbs!
Clutch will be a McLeod single disc 12" dual friction, and the flywheel will be an aluminum McLeod modified for the 12" clutch.
