Convertible interior's

My 67 Dart looks to be same panel with gloss black upper, and stippled lower panel mono tone color black to match black interior with same chrome strip. The difference looks to be two-tone color scheme.

If you remove that panel be very genital particularly when releasing it from door jamb, as it will be apt to crack. I repaired cracks in my plastic side panels with plastic repair epoxy, also plastic welding machines may be capable of repairing these cracked panels.

If you are looking for factory fresh look, than I suspect new panels are needed.
