My 64 Bird converible no longer has the heater box,fan etc - just the control unit on the dash connected to nothing!! I have the old heater box but it is in sad shape and some of the connecting rods and flex hoses, but it appears it would be difficult to get all the parts and reinstall - anyone ever have the Classic AutoAir system from Tampa FL installed on their bird - looks like a good retrofit system
