That looks more like a tray to put your Happy Meal on than a seat.
Fast war story, years ago back in the early 1990s, I was buying my 2nd WC54 (WWII Dodge 4x4 ambulance). I was at a trucking company that owned the WC54. They had used it for 20 years as a mobil repair shop. I was asking the owned of the company some quistons about the truck, there were a couple of his workers in the room also. I asked if the truck still had the map board in it. He looked at me, and slowly said, "map board?? I do not think it has that" One of the workers even asked what is a map board? I told them it was the wooden board that was mounted under the glove box on the truck. At that moment the intire shop at the same time said " YOU MEAN THE COFFEE CUP HOLDER!!!!"
It was still on the WC54, in ment shape, with a slight smell of coffee on it.
