Hmm, swap gears, or swap the entire rear axle assy? Swap gears to a 3.54 which includes gears, installation kit and a different carrier, put in a posi? maybe. Swap an entire axle assy, 14 bolt good diff, almost bullet proof strong. Lets see, pull old one out, pull driveshaft out, (gonna be a different length), New u-bolts along with the lower plate that fits the 14 bolt tube diameter, more often than not cut off the spring pads and shock mounts for relocation, cut the shock mounts off of the d60 for reuse. Mount the axle in, center it up drop it on the ground, set the pinion angle weld it up and finish bolting it up. Weld the shock mounts to match the original. Measure the driveshaft, going to need a longer one. Parking brake cables..........cut the rivets off the original frame bracket, move closer to the diff because the 14 bolt cables are shorter than the d60. Weld, fabricate something so they fit and will droop correctly when you lift the truck, measure for a new .....longer intermediate cable and order. Hit the auto parts store and find the correct hydraulic hose for the brakes because the 14 bolt uses 3/16 hard line instead of 1/4''......... bleed brakes.
