Just bought a 65 C60, question about brakes

[alabama mike]

I just bought a 65 c60, it was a farm truck all its life I bought it from the original family that bought it new, truck is show 60,000 and the old owner swears its correct. It has a 292, 4 speed, 2 speed rear axle, its a flatbed dump.

My plans are to cherry the body out repaint and just use it around the farm to occasionally haul gravel and hay. The old truck had been sitting up 19 years, we've done a little work on it, rebuilt carb, new fuel pump, cleaned the tank and the truck runs like a top. my next project is reworking the brakes, because it doesn't have any right now. so I have a couple of questions.

is there any type disc brake that can be made to work on this truck? can you put a dual reservoir master cyl on one, I did the same on my 65 C-10 it would be nice to be able to do it on the C60. eventually I want to upgrade the truck's power train, thinking upgaded brakes would be a good thing. any help would be greatly appreciated.
