Don't beat yourself up over the other green one, I also passed on a few of Cliff's project status '69 Y-Camaro's in that price range - but I was ass-deep into the deuce
The guy with the couch doesn't know that it's from a Yenko, neither did the guy who wrecked it and parted it out. When he bought the car it was red, SB, a/t, SS stuff all over it, etc.... He swore it was an SS, till I asked him if he ever found any green paint on the car. He was shocked, and revealed that it was indeed green under the sill plates - he about fainted when I informed him that he totalled a highly optioned Yenko Camaro from PA.
Just to be safe, I asked him where the firewall went. He replied that the damage was so severe that the engine was shoved into the firewall and pushed it back several inches. The driveshaft came up through the floor boards, the roof was bent and twisted as were the rockers. I'm trying to find a pic of the wreck, but no luck so far. What a shame.
