73-87 1 Ton Brakes on 67-72 C-30??

[67_C-30]

I have a '67 C-30 that I making into a Dually pickup. I have seen several buildups that other people have done claiming to have 73-87 Disc brakes on a '67-72. Can anyone tell me exactly what is needed to do the changeover?? Is it as simple as just changing the spindles and ball joints, or is it more involved than that?? I already have an '81 C-30 Dually parts truck with good spindles, rotors, calipers, etc. I am putting a 6.2 diesel in the truck, so I will use the master cylinder, hydraboost and proportioning valve off the Suburban that I am getting the engine from. Any help would be greatly appreciated! Thanks,
