We saw one for sale at a wrecking yard (Russ' VW Parts) in Duarte, CA. back in 1989. It was a red '70 Challenger, red interior, & white painted top, 383 4-bbl., & flat hood. It was all there - very rust-free car & complete, but needed EVERYTHING! WSS car. I really thought it was neat & could picture it restored, but passed on it. Oh they existed allright! I've seen '69 Darts with the WSS package & decals too - saw one in Phoenix in the mid-80's. Probably a /6 or 318 car.
