Convertible trunk mat/sound deadening

I’m looking to get a trunk mat for my 67 Barracuda convertible. I think maybe this classic industries mat is just labeled wrong but can somebody confirm for me? It says fastback but it looks like it could be the one I need.

Aside from that, anybody recommend a different/better place for a trunk liner? Classic industries seems reliable which is why I started there.

Lastly, how impactful would it be to put dynamat or something similar down on the trunk floor prior to the new mat?

Any advice would be appreciated.
