68 Dart Grille Centre Piece

Hello, I'm looking for the centre piece that was fitted on some 1968 Dodge Dart GTS front grilles. Some people call it a nose cone. It bolts on the front grille, in the middle. I know there were some repos made. I'd be interested in either an OE part or a repop part. Does anyone have one they'd like to sell or know of anyone who sells one? Any help very much appreciated. My car had one but it was removed before l became the owner. Best regards.
