I've been working on this car, a Dearborn 65 coupe with a scheduled production date of March 30th, 1965, off and on for the owner over the last couple of years. Mostly just little things to keep it chugging down the road, but, I did recently put a fresh motor in it, and now the owner is all pumped up about making the car both a little more presentable and safer to put his kids in. I was installing a cross piece behind the rear seat to attach shoulder harnesses to and had to remove the back seat because there was some welding involved, and found this attached to the seat back. I have never seen this before, so, I sent a picture of it to a couple of people that might have seen such a thing, and, they apparently sent it to people, and so far, nobody has seen it. So, has anyone ever seen this before?
