Well Jeff, since you are from Cleveland, you are automatically considered nuts, with and without the assistance of paint fumes...

On a serious note: new challengers have the ability to run the billboards.
There have been a few people that have created them.
The issue with the billboards on 70-74 challengers has to be the section of the A-line.
The highlight interrupts the shape of the billboard, making the billboard a split graphic- something that the designers did not care for.
That being said; one has the freedom to create whatever one wants in this country.
I won't throw the Mopar rule book at you, I promise.
