I am thinking of purchasing a '14 roll over and swapping the cab from my '09. I know all wiring and dash would need to be changed. Does anyone know if the cabs are the same as far as the shell goes. I would think door panels and interior should interchange but what about HVAC since Ford went to a expansion valve on the evaporator in '11. I don't know if the openings on the cowl are the same. That's the only issue I can see.
