rocker panel molding clip part #6002840

BTW push out the center post BEFORE you try to remove any of those or similar clips as the center post acts like a wedge and pinches the ears of the clip to the body panel. if you can get to the underside puse it out to the outside of the car, if not push it in to the body panel or maybe drill a small hole down the center and try a screw pull it out to the outside of the car.
