I checked the Autozone and Chrysler parts sources on the WWW and find that the part is readily available, competively priced and interchangable from MYO's 2003-2009 from both sources for the NA 2.4 liter FI engine manufactued for North American applicatiions.
It is quite obivous that the pricing supplied to you was in error and not an attempt to "steal from you". But what's the fun in saying that an error was made when you can slam the dealership parts department.
