First, if I have placed this in the wrong section, please excuse and move if necessary. What is the stamped metal part called that attaches from the rear suspension to the car body at the very rear of the rocker panel? It is held in place by 2 studs at the rocker panel area, and 1 long stud at the other end that goes up thru a rubber donut into the frame I believe. I removed mine today , passenger side and its rusted all to pieces. If I can identify the part, maybe I can buy one somewhere. Thanks in advance.
