I can't answer that because my experience with these problems was gained as a mechanic at a local Dodge dealer. I would say that on your way to the dealership, try NAPA and other parts stores on the way. I will tell you one thing I know from becoming friends w/the parts manager at that same dealership. Whatever they charge you at the dealership is 70-100% over what they paid for it, so, knowing that may give you some bargaining power when and if you have to go to the dealership for anything.
