I need what Saab calls the Antenna Rod for the OnStar Telephone at the back of my 2003 Saab convertible. It's really just a black plastic hood, or casing, that encloses the actual antenna. The part number is 5260575. Here in the States it costs a bloody fortune -- around $95 for what amounts to a small plastic casing that screws into the rear fender. Does anybody have a lead on this part, new or used, for a more reasonable price?
