I guys,
Newcomer to this forum, I already apologize in advance for my naive and irrelevant questions.
Staring at some pics of a Superformance 289 replica, I noticed the two (pull) air knobs located on either side of the dashboard.
What is their purpose ? Is it meant to control the floor heating flow for each occupant of the car ?
Thanks and have a good day.
