to me is strange to spend the money for the color change and not do the door jams. one can't tell but as it is a 73 unless it was special ordered it most likely on of the Velor materials in the car. GM was big on them in there top end cars. they all wore off the knapp quickly and a ash off any one of the smoking devices of the day wold burn deep into it right now. hatted to see on come in the shop as it seamed if some one lit the torch in the far end of the shop you were changing a door trim pad.
