Have you thought about a hydraulic pedal?
Wilwood has a nice pedal setup. For the throwout you could use a bellhousing and slave cylinder from a mid 80's truck or, a bearing retainer mount style.
The Chevy Colorado used a slave that mounted on the bearing retainer, it may be adaptable to other transmissions.
It would be a heck of alot cheaper than the kits that are out there.
