Pete, I've never run a manual system with 4 wheel disc. I would recommend something like the Wilwood setup or something similar. You will need to modify the pedal setup to get that to work. The setup you have now uses either the manual or power Mustang II master for drum/disc. The 4 wheel power disc typically uses a Corvette master. If you try the Mustang II manual master you will need a different brake pedal. I don't know of a direct manual replacement for the power master.
