The Ford 8.8 we are interested in comes with a pinion flange instead of the more common U-joint yoke found on domestic axles. You can swap on an aftermarket yoke or leave the flanged piece in place. A mating piece can be taken from the salvaged Explorer driveshaft and will accept a 1330-series U-joint, or you can do what we did and purchase a Dana Spicer 2-2-1379 conversion flange that will mate to a standard 1310-series U-joint found on Jeep Wranglers. Aftermarket yokes are also available to bump the joint size up to the heavy-duty 1350 series, if desired. Be sure to grab the mounting bolts for the yoke when you get your junkyard axle.
