I have a compressed bumper mount shock on one side (both front and rear) and was wondering if the can be pulled out or if it needs replacing once compressed? There is no damage to the actual bumper itself. It's a 78 wagon and I assume the rear mounts are the same as the El Camino... can anyone confirm? Are the front shock mounts the same as all Malibus/El Caminos,Wagons? I need one front and one rear. Thanks!
