1968 Dart stripe

I have recently bought a 1968 Dart gts. From all things I can tell this car came from the factory in b5 blue paint. The strange thing is that all the other Darts I have seen have had the stripe over the back of the trunk, This one a has the stripe down the side of the car. It's a white stripe and runs the whole side of the car at the parking light height, one solid stripe with a smaller stripe above and below. Let me know what you think, Thanks, Dan.
