You sound very sure of that fact. What kind of evidence do you have? I for one would love to believe that the records exist and will turn up. I have a very good friend that has worked at GM for over 30 years. He's got friends all over there including friends in the archives. Even his friends in the archives have been digging to see if something is around. Many of them are true car guys that would love to find a stash of paperwork. Nobody has found anything. I guess there's always a chance, but in this case it's almost too slim to measure.
