Why not do what I did. Take off the flaps you have and turn them around and put them on the opposite side of the truck. Spray the advertising with black undercoating and then you no longer see it.
If you want to add some decorative chrome or Dodge logos, just drill and attach them to the flap before you mount the flaps.
You can do this if you want to save some cash for other accessories and/or want to use what you already have. If not, there are many choices available.
Good Luck,
Chuck
