The Disc/Drum master has a larger reservoir for the front then the rear, and the brake proportioning valve looks similar, but is different. Do some more searching on the forum, there is a lot of good info. This is where I learned about it.

Ok excellent thanks for the good info. I will continue to research and figure out exactly what I need and source the parts. That's half the fun of these old trucks is everything there is to learn about them!
