Yukon Dura Grip differential for Ford 7.5" rear ends$500
For Sale by Owner
Yukon Gear YDGF7.5-28 Dura Grip Limited-Slip Positraction Differential [Ford 7.500 in.] 28-Spline Axles
Only 800 km on it, used in my Locost 7 replica. Can include the 3.45 ring and pinion if desired. I installed it with all new bearings and was pretty meticulous about getting the shimming and backlash just right. Was in a Ford Ranger 7.5" housing but apparently it fits a bunch of IRS and live axle applications, do your research.
