SIXTO:I just jacked up the rear of the car and looked for the salt shaker thing you discribed and all i can is a very large U shaped thing that the shock is mounted to.I also can see a plastic part just behind the rear wheel back plate. It has a 1/2" bar attached to it which runs up and across the rear of the car behind the gas tank and attaches to the same assy. on the other side.When i realeased the jack, i measured the hight of the rear bumper,and now both sides are the same.Before the drivers side was 3/8" higher.??????
