You do not have to buy these parts through a Ford parts department. They are available through auto parts stores and many "on-line" parts distributors. The compressor is a NipponDenso 10P15F and is SHO specific. It is different than the compressor used on other Ford products. The condenser is also readily available as an aftermarket part.
Keep in mind that these parts are not manufactured by Ford and there is no reason to buy them from Ford.
