WTB 69 Barracuda Formula S Tail Panel
Not sure if Layson's is produced by the same outfit, but you can contact Metro Parts and see if they have any in stock. I think that these are batch produced on an "as needed" basis. Not sure on the quality, and I do not know if other members have purchased from them or not. They LOOK to be a nice piece.

I just missed a Formula S panel for sale on craigslist not too long ago...it was from a guy in Denver with a 383 project and to be in really good shape. Missed it by a day or so...originals do not turn up very often.
