    best to find a donor axle to get all the parts on, you need knuckles out i think..... also need new brake lines a disk brake portioning valve, a booster from a 86 2wd CAN work but it requires drilling holes and other stuff..... best to just find the power brake setup off a 71-72 truck.... get the proptioning valve, booster, master cylinder, booster to firewall brackets, and pedal rod,
    i am currently doing this exact same swap but i chose to just bolt in a whole diffrent axle, which is probaly the easist way to go if you can locate one with the gear ratio you want

    It is possible to buy everything new except the booster brackets. The spindles, caliper brackets and hubs are available new from Spicer but they are expensive. A donor is definately the way to go, preferably later than '73. GM switched to bearings in the spindles around '73. You can use the brakes off of any GM 6 lug up to the early eighties for sure maybe even up to '91? The brake booster brackets and prop. valve can come off of any '70-'72 GM Pick-up with power DISC brakes. (you can use 3/4 ton brackets but the 3/4 ton has an extra bracket you don't need) GM still makes the prop. valves, I got one from ChevyDuty for $50. In-Line tube makes really nice brake lines for $150, well worth it. Get the brake hoses from an Off-Road place, I got Skyjacker, steel braided, for a 2"-4" lift for $50. Stock rubber ones are $30-$35 each! Your locking hubs should fit. You also need the outer axle shafts from a disc brake truck (also available new). Make sure you use Spicer U-joints on the axles! email me if you have any questions.
