Try a dealer that sells online parts. My dealer sells the same part cheaper when ordered online.????
Bob Utter Genuine Ford Parts www.bobutterfordparts.com
This is for Bob Utter Ford (Thanks Stlwagon) they have good prices on stealership stuff. But try different online dealers parts as I have seen some of them have cheap pricing on some items and higher on others.
I maybe wrong but Im sure you will need a Genuine Ford part for a direct match.
Also try a junkyard (you pull or otherwise). Then again around here any new Stangs are stripped bare really quick if they even have any as people will take a totalled car and bring her back to life.
