You said you called the dealer, was that the Chrysler dealer or the Mercedes Benz dealer? 1705450305 is still a good part number with Mercedes-Benz and it's a lot cheaper, call your local Benz dealer and give them part number but don't tell him it's from a crossfire and see what their price is you may be surprised.
