Cool thread...FWIW, All of the circle track late model sportsman cars that my father and I built (more so my father) in the late 60's through the 70's, used new GM Chevelle/Camaro sheet metal. These cars were built using '55-'57 Chevy frames with various spring set-ups.
The car above looks to be more of a LMS car than a Street Stock.
That being said, most of the SS cars were taken right off of the street and raced.
