hydrolic?

I've driven cable, linkage and hydro clutches and the hydraulic ones are smoother, not necessarily faster. I'm getting ready to do a 4-speed swap with a hydraulic clutch setup, and it's really only as difficult as mounting everything. Now if you are using the stock stuff that bolts to the bell, then you are half way there. You'll need to pull the z-bar and run the z-bar pusher to the clutch master cyl or fab a push rod after you drill a hole in the firewall. Is the master cyl from the truck plastic? I went to the local yard a pulled a alum 5/8 bore master and a metal slave cyl to build mine, didn't like the thought of a plastic one..
