I'm running manual disks/drums witha "power" master cylinder off an '85 1/2 ton truck. I priced a non-power master cylinder and it costs twice as much as the power one. Not sure if it'd make THAT much difference in pedal feel. I'm happy with my setup and left the other two holes in the firewall in case I decide I want power barkes in the future. I used the later model MC because it's made of aluminum and palstic (no rust).
