Kevin!
No worries! The trunk lid came orginally with holes just for the letters for the basic Dart. There were centered between the tail lights. If you added the trunk lid car for a Dart 270 you used the centered holes for the letters and you had the drill the holes for the upper and lower moulding. Finally if you had a GT you had the add the holes above the upper moulding. But for the cenetered holes you had to add a piece of tejp.
