I found that the easiest way is to do a complete front end swap with a 71 or 72. If you can assess the condition of your front suspension, steering linkage etc. and if you find you will need to replace some things anyway (like ball joints, tie rod ends, etc.) then that is the way to go. Just find a donor truck of those years with better susp./steering components. Its much less hassle than having to pull everything apart. You would need the master cyl, prop. valve for a disc brake truck. If your booster is still good you can use that. 71 and 72 wheels are 5-lug, btw, so you will also be needing to change rims unless you pick up some aftermarket 6-lug rotors.

I heard that rear discs from late 70's Cadillac Seville will fit our trucks with minor modifications. But I won't go hunting for that setup unless its right under my nose for really cheap. Most of the important braking power involves the front brakes anyway.
