They are repop panels, nothing embossed. I have seen them embossed like you are talking about. I went ahead and bought a sheet of .060 styrene plastic, made templates and pop riveted to the back of the panels. Then made styrene fillers to glue to that, the styrene forms fast and easy with a heat gun. Now we can build on that with landau foam and shape the panels for the look I'm after before covering in leather. Doing something different for a second gen. with the rear and door panels, also a twist with the dash.
