67 Barracuda rear seat ornament

I was looking through eBay at other 67 notchbacks, and I saw an almost-rectangular emblem with a Barracuda located high in the center of the back seat. Is this typical for all 67 notchbacks -- or just certain trim packages? If it was original on my car, I'd like to put it back.

I saw the item itself on eBay and it looks like there are 2 studs on the back for mounting. The back piece of metal on my car has two holes. I know the emblem mounts on the indented upholstery and connects somehow. Would the emblem studs mount directly to this metal piece, or is there some kind of bracket that goes between the emblem and the back piece of metal?

The coverings on my back seat are pretty shot. I can't really tell what was original.

Thanks in advance for your responses.
