I know by the looks of it this is the opposite of what you guys are trying to do but i have an 86 iroc w/o ac and i would like to put ac in it... I certified to work on air conditioners so i understand the system but you guys have a better idea of what is behind the dash and what is different from ac to non ac cars... i would like to swap what i need out of a donor vehicle if possible... anyone tried this yet???

 

if the car is a non ac car from the factory, the ducting under the dash and the controls are different. You need everything, all the ducting, the control unit, all the cables, vacuum canisters hoses valves ect, as well as all the parts from the engine bay.
