I had integrated one end of the panhard bar mount on the rear diff (under the RH lower bag mounting plate on the rear diff), now I needed to build a mount for the end that attaches to the frame.
I went ahead and temp installed the two airbags and rigged the panhard bar assy (that I had bought from Speedway Motors) at mid adjustment. I then figured out where the frame clevis needed to be on the frame with the rear suspension at mid-travel (up/dn) and fabbed a double shear clevis out of plate to weld to the frame.
