For a US 69 GTV: In the bumper center section, right under the license plate, there is a recess between the bumper and body of the car where the light shines up. The bracket that holds the light bulb is nestled within the concave portion of the bumper and riveted to the inside, lower lip of the bumper. Not easy to photograph but maybe someone has a diagram with exploded view?I appreciate you posting the pictures, but I can't tell where the license plate lights are...
Are they 1) "frog eyes", sticking up through the bumper, or 2) recessed, and shining up through a "cut out" or "notch"?
Or none of the above?
