Here's a link to the hydraulic setup I used in my 1960. Something similar could easily be done in a 66. I found the components I'm running provide a considerably lighter pedal pressure than the original setup. I'm running a Centerforce clutch, Girling master cylinder and a Novak slave cylinder. I have chronic back pain and a bad knee, so a light clutch is essential to keeping a stick shift in my rig.
