I just finished the project this weekend. I had done the 5 lug disc conversion from a square body truck. So of course, I changed the brake booster and master cylinder too along with prop. valve all from the square body. My 69 had the same prop valve as you have in the pics where one line is for the rear and the other to the front brakes. I ran the one to the rear with a union but had to run two individuals to the front because thats how the square bodies are. Pretty simple... took two lines, bent them, and took the t adapter off and ran one line to the left and the other to the right. any questions let me know i could try to guide you thru any obsticles.
