The script with the short curved leg on the "r" is for the left front fender extension. The rear quarters have a long straight leg on the end of the "r".
Did the 69 have a Mercury script on the trunk lid? I can't remember. I know my last one did, but I may have put that there. I don't believe that my current one had one. I know it had the XR7 letters on the right side of the trunk lid.....
