What you describe is a 'camber-lock' and similar devices are sold by all the Pantera vendors. Some have better installation info than others. I'm not sure who made yours from the description. Basically, the camber adjustment in our cars is via slotted holes through the upper ball joint holder & is held in place by simple bolt compression- a VERY bad design. The camber-locks jam the adjustment so hitting a curb or pothole doesn't instantly change your wheel alignment.
