My advice is to go on one of the aftermarket disk brake suppliers, ECI I think has a good/ clear easy to read instructions and read completly as it relates to your truck. One of the many things to consider is if the wheel cyls are parallel to the MC if they are you need either 10 lb residual valves near the MC for durm/drum brakes or for disk/drum 2 lb for the front disks and 10 for the the rear. Replace the MC with a Corvette unit. Many things to consider, none more important to do your brake system correctly.
