'71 LS6 Chevelle SS existence
I found a possible Holy Grail 1971 LS6 454 SS Chevelle. Many say they don't exist. I read a thread on here somewhere where a guy actually took the plastic off one and prepped it for a customer back in '71. Stories of 10 automatics and 4 4spd ls6's. How can I prove that the 1 my friend has is a true original factory 4spd LS6 1971 Chevelle? And what would be the potential value of said car?
