Terry:
Here are the measurements from my 1966 fender. My apologies, but I didn't have a camera to provide a picture. Let me know if this works or I will round one up.

Center hole for the lights is 1.25" in diameter.
This hole is centered 5 3/8" from the edge of the fender where it meets the bed of the truck and 7" from the body line of the fender down to the hole.
Additionally, it has two .25" holes on either side of the center hole for the bolts that hold the light. These two .25" holes are at 11 o'clock and 5 o'clock positions on the center hole. These two .25" holes measure 1 7/8" from center to center.

Mark that off and see how it looks compared to your lights and let me know.
Regards,
Steve
