I just bought a 2008 Classic 25FB. Have you tried looking at the 2008 Classic Parts list document? You can download it from the Airstream site. If you find the part then plug that parts number into Google and see what happens. Also try uploading a photo of the part so we can see what you are talking about. I bet all the major Airstream dealers would be able to get you that part or worse case Airstream themselves.
