There was a site I saw years ago that had picyures of every color TA and AAR made. They weren't all on one picture but there was a page that had the links set up for each picture. There was even a link for a claimed 1 of 1 Petty blue AAR (I have no idea if it was a real factory car).
I used a setup from him in my car. I bought it at Carlisle but he had to ship it to me after the show. It showed up a couple of weeks later and so far it has worked ok. I haven't seen him at the Carlisle show for a couple of years now.
