This is the round bar on the Dunlop AGO/40 Toe Gauge that runs parallel to the centerline of the car, along the floor. All assemblies attach to this bar (arms with contact pins, calculator and view box, etc). A bent bar will throw off the accuracy of the gauge.
While supplies last! This part will not be backordered.
