    Default 1980 dash hvac system

    I have 1980 cobra was a turbo 4 cylinder car swapped a 82 gt drivetrain into the car. Had to take the dash and the hvac box out to replace the brake line that runs in the car. I'm puting the wiring harness back in the dash from the 1982 gt. Does the vent box just sit there up agents the center vent under the defrost vent? Does anyone have a photo of how it's supposed to look? Thanks

    The main Evaporator/heater core box is bolted to the firewall and has the additional bracket that attaches to the bracket just below the windshield on the inside. The ducts and vents are installed in the dash assembly and then sits against the opening in the HVAC Box and have a thick foam gasket that seals the duct work to the box. The lower heater duct has some screws/bolts that attach it, but I don't recall right now if that attaches to the HVAC box or the lower section of the duct work. Hope that helps in some way. Good Luck!
