ahh thanks, I was hoping the whole faux cover would just come off without pins. So specifically I am wanting to replace it with my howler badge, will it cover the holes you think?Are you talking about the thin plastic overlay with the California Special language or the entire faux gas cap? The faux gas cap is attached (pins etc) to the gloss black panel piece.
You want a clean rear panel you replace the entire rear piece. Simple to do-Ford sells the entire blank panel-warning some folks report mild dimples in the blank panel from the molding process. Run a search on the exterior mod threads for details and pics on installing.
