Hy bigblack'74, the 1960 through 62 trucks which had air brakes used a single clutch master. I don't know how much room, if any, you would have in the stock location to mount a clutch master next to your booster/master cylinder. I think you will have to mount the clutch master more toward the middle of the firewall, and fabricate your own linkage to it, good luck with your project.
