One thing you'll have to have before you start installing is the solid axle. A Dana 44 from a '78-'79 fullsize Ford will fit perfectly, and absolutely no welding would have to be done for this kit. Unfortunately, these axles are not always readily available. If using an axle other than this, make sure to use one from a fullsize vehicle with a driver-side differential, such as the '91 F-350 kingpin Dana 60 axle we found in the classifieds for $1,500. This axle was the perfect width, but we had to cut the centersection on the driver side right next to the plug welds to make enough room for the radius-arm axle brackets. We also shaved all the factory brackets and mounts off the axletubes to make room to weld.
