See if you can find a spec sheet for the two.
You might find that you can mess with the proportioning valve and balance it all back out. Worst case you end up playing with getting the right one. Look up the applications chart for the MC and then look at the trucks it was mounted in. Then see what the proportioning valve is. I may be using the wrong word for the proportioning valve -- the one under the hood for the Dodge. Old Volvo's had a rear proportioning valve that was adjustable (2xx series). Then there are the rear brake load sensing anti-lock proportioning valves a lot of tricks use now. They are mounted between the axle and frame, using an arm that moves with the axle returning excess brake fluid as the front dives (lengthens the distance between the frame and axle). They might be useful in rigging up a reasonable tunable system. Bet they are cheap at a junkyard. IF you need on.
What did the D600 use for brakes?
Also, Dodge sold a lot of these trucks in Mexico (not sure D500 or 600). You might have some luck with that.
I bought a 78 D200 USAF truck in the late 80's. 51000 miles. No fins on the radiator, even with the rear seat heater on and a light ran it was running hot on the 20 mile drive home. Anyhow, at least for the D200, it was built to contract spec, not the average spec you would have found at a dealer (front rotor to wheel bearing seals were D100 sized for example). It was the last year of the in cab tank -- worked in my favor when the fuel pump died and we pushed it to point downhill (just lucky). There were other not quite D200 parts on it, but nothing that big a deal.
Even if it is the wrong MC, you're out $50 to find out. I bet it works (oh, and a couple of brake lines).

On that Cornbinder 1700 -- I have a 71 D100. The interior/cab parts for yours are a LOT cheaper. Guess the cab for yours being made from mid 60's to 1979 must have some volume to it.
