69 gmc 3/4 ton brake conversion

[mikewarme]

Here is what I have. A 69 Gmc 3/4 ton camper special with a 396.
I have installed 71/72 Chevy truck steering knuckles and ball joints, rotors and calipers. I bought a new booster/master cylinder set-up with proportioning valve. Does anyone know of a brake line conversion set FOR the 3/4 ton 69 year? Or can someone explain how its piped diffrently than the current drum set-up. I understand that the front left and front right go seperatley to the proportioning valve. Is this correct? I have called every place that sells the kits and knowbody can help me. How pathetic to sell a kit and not have someone that knows details. I am doing a very clean rebuild and do not want to Mickey Mouse it.

Thanks for the help Guys/Gals
