For the Bronco owner that is swapping front axles, these wedges make it much easier. No need to cut up a good front axle just for parts. These wedges are designed to weld onto a 2 3/4” O.D. tube, just like a factory Early Bronco Dana 44 but are easily modified to fit onto 3” O.D. tubing found on high pinion Dana 44 and (Dana 60 will require grinding or using 5351-60 Spacers). Cast with all the correct configurations to fit the inside of a C bushing exactly like original.
