Such as thing as factory power windows on a 2-door '74?

No Dart, Demon, Dart Sport, Duster, Valiant or 64-69 Barracuda ever came with power windows from the factory. It was never offered.

yup. it was on the fender tag and the build sheet. I've seen and sat in the car several times as have several members of the club. Chris and Thomas Ritchie had that car. Sold it to some guy up north that actually had Galen hisself document the thing. It was factory. Car was pretty well known around here for a long time.
