I have pics here of the '69 Coronet emblem on the rear, and the '70 Challenger emblems on the front panels, with king-size pics linked.

Get the deck-lid versions if you want stick-ons. Personally I think the vintage emblems are the way to go with this car. I'd haul off the new r/t if I had an '06. Makes a direct connection to the term 'hot rod' without even having to step on the gas pedal. An instant nut-shrinker for that ricer in the next lane.
