1967 Plymouth Valiant 273 Commando 4-Speed

I am ashamed to say I was responsible for the disappearance of one of these cars. In the mid to late 70's I bought a 67 4speed Comando Valiant. I don't recall a bunch about it. It was light green and had red bucket seat interior. I wound up trading it for a 66 GTO convertible. 389 4 Speed with a 4.30 gear. Well the guy I traded it to yanked the little 273 and 4 speed, tubed the car and dropped a 440 4 speed in it and drag raced it to death.
Years ago I got a Commando 273 from a friend who had it in his 67 Barracuda (an original 383 car) when I asked about the history he said the guy he got it from removed it from a Valiant as he was building a race car. Same car? Where was this?
