There are several sites out there with info on Trans Am cars, Barry's and Jeff's seem to be the most comprehensive but they do not have all built just all discovered. I think the count is up to around 1300 of each and includes what they know about the cars except private info but they will assist in putting people in touch when needed. Everyone that knows about them shares anything they find but there are some who do not know them so there is no doubt plenty more info yet to be discovered. Many of us take pictures of cars and tags across the country at every opportunity and send it in. There has also been several reunions that brings new information.
