Seat back paint

Does anyone know what sheen the paint was on the hard back bucket seats in 67? Was it a satin, semi gloss, or gloss. I also have the same question for the interior doors and trim around the back window for my 67 Barracuda. Mine is black, but someone has painted the stuff in the past and I can't be sure of what would have been stock. I want to strip and repaint. Thanks
