Ok, last weekend was the Chrysler Nationals in Carlisle PA. They have on their site a list of vendors who sell parts. I bet one of them could direct you to the part you need.
www.carsatcarlisle.com. Click on the vendor list right below the info for the Chrysler show. It comes up in PDF file and some have addresses and some phone numbers you can call. Also, did your dealership do a nationwide search for NOS parts? I bet someone out there has one. Good luck
