I guess no one responded because this has been hashed out here previously. Chevrolet has never made a statement, I expect they could care less. Some Corvette guys were granted access to a storage facility and found records only back to the late '70s. It is a bit much to expect a Chevy to maintain hardcopy records on the millions of vehicles built in the last 35 years although I suspect the info could exist on mag tape. Just ferreting out the first-gen stuff (700,000 records) would be a massive, incredibly boring task.
