So I bought a 1969 Super Bee almost a year ago. Beautiful car, great powertrain. Fixing some dumb stuff and going over it. The car had NO heater core, nothing, no heater box or any of the parts necessary to get heat. Everything was blocked off under the dash. The car runs fine BUT I like to have heat as I drive year around and if the car runs hot I can run the heat to help the car. NOTHING is the car is stock so an aftermarket setup is fine. What is the best route to go? Stock or the heat and defrost system from Vintage air? I am NOT interested in AC. The car is a NON A/C car with a Hemi in it. There are NO provisions in the firewall for the heater hoses. They closed them up when they smoothed the firewall. THX in advance Scott
