manual to power brake question?

[skeeterbug]

hello all, i am in need of some input from those of you whom have done this upgrade already please. i have a 71 c10 lwb that i have doing a frame off on and need some suggestions to convert it from maual to power booster brakes. before i tore the truck down i purchased a complete ss brake line set from LMC, it has all fit fairly well till i started plumbing the lines from the mastercylinder to the front crossmember. the master cylinder and prop. valve that came w/ my truck i belive came off a earlier model c10 and will not work w/ the new ss lines. i have since picked up a donor mastercylinder from my fathers '56 belair rebuild we never used, its better but the ss lines still will not hook up correctly to the old prop. valve i have. to make a long story short i have decided to go w/ captain fabs disk conversion brackets, willwood d52 calipers, and astro van AWD rotors for the rear. for the front i will get two more d52 willwood calipers and cptain fabs booster braket, but i need to know what prop valve and booster to get. will the stock 71-72 style prop valve work or will i need to get a disc/disc prop valve, please help i might as well do all this s@#$ while its this far down and needing a different valve anyway.

thanks
