Classic Auto Air comes with a plastic vent that screws onto your center dash. Very not original, very plastic looking. It does have directional controls that the original does not have.
I bought the original style vent and had to cut a strip of plastic off of the air vent mount thing from classic in order to get it to fit, and use some weather stripping to keep pressure against the original style vent piece. It looks and works fine.
