thanks 3B that part number will make all the difference, i'm gonna have to get the pressuure valves for the front and back brakes, i got the big 14" drums with 2 1/2" shoes on the back and 12" drums with 2" shoes on the front, i'll never be able to upgrade to dics if you know how to do that i'm all ears, do i need to plumb the pressure valves close to the master or anywhere in the line to the drums? what size brake lines do i need to use with the valves? does it matter? i got the stock lines on the truck now i think they are 1/4" does this matter? is this master just an aftermarket universal master or is it for a specific vehicle alot of times the flaps guy's only can look it up if they know what car it fits. thanks again for the info
