64 65 66 Cuda top qtr. panel fender spears?

If my memory serves me right! I remember removing the rear door panels. They are secured with a "pinch" clip. You have to pinch the bottom end of the clip and push up ever so carefully because these spears bend easily and pushing up hard will definitely bend it. Reinstalling them is easier. Align the clips and pinch the clip to get it seate in the mounting hole then apply even pressure on each clip.
