Apple Portrait Display: Cable Part Number

I have an Apple Portrait Display monitor and a Portrait Display Nubus card. Unfortunately, it did not have the cable that goes between the card and display. This looks like a very special cable, not the standard 15-pin type. Where I can get this cable?
A local Apple-authorized service provider can order one of these cables for you. Either cable will work. Note that one cable is 25-pin to 25-pin, while the other is 25-pin to 15-pin.
