They are AMT '56 Fords. I build them about the way they used to build the real race cars back in the day. I take a street car, throw away everything that doesn't look like a race car and start from there. LOL
Actually, the "stock cars" back then were a lot "stocker" than the one of today. They started out with a production car and added roll bars, heavy springs and shocks, some tweaking and painted the markings on and went racing.
These two were from Nascar's Convertible Division that ran from '56 through '59 and the background photo is from the old beach/road course at Daytona that used a two mile stretch of highway A-1A and the beach for the return path.
