Well I went back to the start of your article and saw .Where your ac unit is a dealer installed unit. I kept looking and nothing came back looking like you. Then I re-read the start and see why. If you have the name brand of the dealer installed unit. I,d type it in the address bar and you might find your parts you need. If you decide to go with a factory ford unit. You shouldn,t have much trouble find it. Their is a company that does sale the old ford ac units. I don,t remeber the name,but I have to replace some parts on mine before long. Good luck. If I find that company. I,ll save it . Sorry I could not be of much help.
