Yeah, both the wagon and SD have no tail light hole. The SD is easily identified from the wagon in that the SD mounting flange is angled where it contacts the body like the regular passenger cars where the wagon flange is not angled, the studs it mounts on come down out of the wood so the mounting flange is flat with the top surface of the fender. Also, the driver's side fender for the SD has no gas filler hole, it protrudes through the rear quarter panel and the wagon has a gas filler hole on the left side fender.
My wagon is done and the SD I had I sold many years ago so I don't have pictures to show you.
