RE: Front licence plate options?
I don't know about the Challenger but the 2006 Mustang came with very tiny holes that the dealer can use for plates but when you put screws it makes them larger.
If tiny holes are on the Challenger just use strong stainless steel screws that are small so the holes are not made larger. You migth have to use washers.
