The vertical grille bars?

Yes, it is possible it's original, but it's also possible it's been swapped from a 500, too.

Sometimes the part number is the same for the base grille, and the paint details or specific trim is/are added later.

Who cares, it looks cool and you have a print ad to back it up. Just like the '71 Challenger T/A owners.

You'll probably never get a definite answer one way or the other.
