What PB ASSY. on the firewall?

The '64 "SuperHawk" had the single cylinder MC under the floor, with a hydraulic tube leading up to the hydrovac on the LH inner fender, aft of the battery. I would advise against that (you don't like the judges anyway) as it doesn't have the back up of a split system. If you're prepared to mount a re-enforcement plate on the firewall and can fit a booster and dual piston PB assy in there, that might do. (Room to change the plugs and get to steering box?) Obviously, the floor will look somewhat silly, unless you have a AT car.

Otherwise, I'd go with Jim.

Malcom, You might want to consider trying the disc setup without a booster. What you should look at is the length of the pedal arm to the pivot and the pivot to the point where the actuating arm to the MC attaches to the pedal arm. If you have one that has a ratio of 7:1, then if you exert 30 lb of pedal pressure the force on the MC piston is 210 lb. The diameter of the piston then determines the fluid pressure. Using the fluid pressure and the caliper piston diameter, one can calculate the force in pounds acting on the disc brake pads. I think you will be suprised with the force available.

If you are going to go the route of a firewall booster I have a booster from an Astrovan that I was going to use in my Lark, but the booster is too long and combined with the MC, the MC would hit the battery. It is a dual diaphragm booster and it has never been installed on a vehicle. It was surplus stock so I got it for a really good price. If you think you can use it you can have it for $50.
