I have a 1963 Grand Prix with a factory 4 speed and A/C. I have recently rebuilt the A/C, which now works, and have purchased the factory ductwork, which was missing when I bought the car. For the life of me, I cannot figure out how the ductwork from the driver's side ball vent is supposed to connect to the main ductwork that distributes the cold air. There is just no space over, under, or around the steering column to install the factory duct. Anyone have any thoughts on this?
