Deck Lid

My friend inherited this deck from an estate auction that was selling off Mopar part groupings. The deck lid had no labels from it's origin. I told my best guess was it being from an old Plymouth Valiant.

So I'm posting in here to see if any FABO members could identify this deck lid. Any help would be greatly appreciated.

It's in mint condition and should go to a project that could really help it out.

thanks
