Has anyone ever seen an SSA Dart

A friend back in high school was a GTO fanatic. After high school in the early 70s he sold his pride and joy 67 GTO and all his Pontiac parts to buy this plain jane white 67 Camaro. That's the day I learned what a Z/28 was and if I remember right its only hint to what it was, was the crossed flags emblems on the front fenders that had 302 over it instead of 327 like my brothers 67 RS convertible Camaro at the time. I could be wrong about the emblem, but my fading memory says it was there. He move out of the area for a job a few years latter and I never saw him or the Z/28 again, that was like 45+ years ago.
