66 Dart Trunk Extensions

Anyone know where to get a set of trunk extensions for a 66 dart, or is there another set out there for a car thats not too far off.. some cutting welding and grinding is not bad, but I am trying to get the piece as close to stock as possible but finding one for the 66 is not happeneing. Someone told me the trunk extensions for the 66 cuda were just about the same....anyone know???? Thanks
