This bar had some damage to the splines that appears to be from someone using a hex-socket of the wrong size. I've repaired the splines and the hex hole, but it now requires a 10mm hex to install the bar. I've also polished the bar (as usual).

It includes a NOS retaining bracket as shown. The fit is snug between the torsion bar and the bracket, but can still be installed and removed by hand.

Because it's less than excellent, I'm offering it for just $549 and with a 1-year warranty against breakage (full refund - shipping costs).
