Hi. Just got a 48 super Conv. And while studying online pictures of others, I noticed that Packard used two different Dash designs? Some have stainless trim in center and a painted glovebox door on pass side, and others have all stainless trim over dash on both sides of radio covering dash face. Is there an option, or name, or particular thing associated with one or the other? Any relation to month built like early or late car? im curious. Thanks
