1969 Dart GT convertible top of fender trim.
The GT trim package was just that a trim package.
You would not order a GT then go with any trim delete.
67 the GT trim was truly on top of the fender door and quarter peak
68 the GT trim followed the lower style line that starts at about fender height ran over the wheel openings to the rear bumper.
69 followed the same line as 67 BUT was fully on the side of the fender and much wider.
Hope that helps.
Post some photos of what you have now.
