When I was a kid, my hero was Joe Lee Johnson (the same guy who won the first World 600 at Charlotte). He drove a yellow Camaro, number J-8, at Cleveland Speedway in Saturday night dirt track races in the early '70's. For many years I promised myself I'd build a model of his car. Your Camaro looks like a perfect starting point for that car. I can't find any pictures, but if I do I'll post them here.
