Here;s the story. In 1965 they were chargers and when dodge came out with the charger in 66 they changed them over to commandos. Thay used up what they had left of the charges lids till they ran out and switched over to the commandos. They had some misc. chargers ones laying around in stock so they used those up as needed.
Absolutely untrue. We parted out a '67 GT back in 1980-81 that was wrecked in 1974. "Charger" air cleaner. I've also seen other '67s back in the early 1980s with "Charger" air cleaners and plenty of '66s with them.
