I've seen the tail panel (the area between the trunk lid and the tail light) on 70 challengers in body color ,Black(organisol?) and that silver color . Is there a rhyme or reason to it ? I cant tell if it has something to do with trim package ,stripe choice , color choice or just random choice of the buyer. Also if you have suggestions for the silver and black color in hobby paint because I don't have one in the driveway so it's hard to tell what they look like in the real world.
