Any retrofit A/C systems for A body?

Any retrofit A/C systems for A body? Id like to add A/C to my 68 cuda, as i intend on taking it on power tour next year......with my wife. Id like to know if anyone's added it and where you got your kit/componenents.

Relax, its a non-S 318 car. Im not butchering anything too sacred to add this to my car

Thanks,

Tom
