My truck hasn't been together for awhile but with the TKO 500 we cut a bracket out of some carbon fiber we had laying around to mount the hydraulic clutch reservoir off of the brake master cylinder/brake booster.
We also bought a hydraulic clutch retrofit kit from a company called Novak that specializes in using GM engines and transmissions in Jeeps. My dad says he wanted an external slave cylinder so it would be easy to diagnose and access while being affordable.
