I know on my charger, the upper door frame plugs that covered the access holes for the vent window frame bolts were interior colored plastic. On our mostly unrestored 69 GTX vert, the plugs were black plastic while the interior is the T7 bronze color. Granted, everything with the interior of the car was all original with the exception of the seat covers and carpeting which were replaced due to fading. I would like to put the plugs back in the correct color if they are indeed supposed to be interior color and not black. Can anyone shed some light on what would be correct?
