check out the PowerMaster system as used on buick grand nationals. I used them on our Cobray-C3's as a remote mounted system. Use a standard 7/8 bore master cylinder on the firewall and run to a hidden or convienantly mounted slave cylinder to activate the powermaster unit. You can also seperate motor and accumulator for ease of install, run a remote resivour for fluid. sounds confusing but maybe just my ability to explain a photo is worth ????
