A few pic of the differences between the A/C and non A/C components.






The defrost ducts are the same and connect to either box the same. You can either keep the manual kick vent and block off that vacuum port or add in the actuator controlled vent. I would recommend physically looking at a truck with the A/C setup to see how things are routed and what you like and don/t like about the factory setup.
