You want to use '39 Chevy car "bullet" tail lights on your AD panel or Suburban. They mount below the beltline. Open the rear doors all the way and mark your installation spot from that vantage point. That's how I did mine 22 years ago ( before they were reproducing those lights) . The '37 Olds lights look nice but the stanchion mount will make the lights stick out further from the body.
