I wouldnt use anything else but the factory air conditioning stuff myself, personally I like the original look its timeless and never goes out of style, I ve gotten to the point where I would have to consider long and hard before purchasing a truck or cab if it isnt air conditioning equipped.especially if the the outer housing isnt cracked or broken the plastic and fiberglass on these things are always bad,so if yours are in great shape you shouldnt have any problem finding a buyer..Just my 2 cents..
