Well, padiddled around with the axle today. Got the Wedge assembly and the axle sanded down to bare metal, cut off the OEM track bar mount and smoothed it down. Also got the axle in the vise ready for the reinstallation of the wedge assembly. I'll probably end up taking it into work for the final weld around the wedge assembly as I only have a 110 MIG.
Next step is to cut down the radius arms, get some 2" OD DOM and make my arms.
