That looks like the one that was on my '65 short, wide bed. It was an engineering accident. It and I went around and around and around every time I had to use the spare. You could lay the spare in it and go to raise it up and the spare would fall off. Start over and it would fall off again, and again, and again. I hated it. That's why I wound up carrying my spare loose in the truck bed. Luckily no one ever stole it.
