i picked up a ac compressor out of a 78 ramcharger. it appears to be a york style but i am unsure. It has a dual cylinder setup and it is a piston style pump. it almost looks like a v-twin compressor. I only paid 50 bucks cdn for it and the clutch so i figured i would take the chance. the clutch works and it compresses air. if anyone know what i am talking about and could tell me if it would work or not that would be great... thanks
