Actually, I think people have confirmed you still need a correct disk/drum MC. Note that all your lines in post #1 are 1/4". Stock disk/drum lines are 3/16" (to front disks) and 1/4" to rear drum. Will it work if you just install a prop valve and do nothing else? Perhaps. Will it work correctly? Not likely - or at least not like a stock disk/drum system was engineered to work. Recommend not skimp on the parts or go crazy with mixing and matching systems - a new correct MC is not very expensive and GM engineered the original brake systems to the truck (71-72 C10 brake systems is the model you'd want to emulate).
