Evidently the show's directors shot a lot of second unit footage around the house that was supposed to be "The Brady House" in 1969, so you see 1969 cars zipping around the house long after they were swapped out for newer models. That's how I just uncovered these two alternate shots from ep. 2.16 of Mike Brady's three star '69 Plymouth Fury III. It's the only shot I have of this particular car's grille.
