I personally don't think we'll ever see any information on Chevrolet cars. Regardless of whether it exists or not. And I don't see why GM would ever be worried about being sued over it. Why would GM have any responsibility if someone bought a fake/cloned car? The biggest risk might be the new privacy laws but that information could be masked out before releasing information. GM seems to be in a downward spiral right now so documenting 30-40 year old cars is not something they're worried about. But I'll keep my hopes up, it never hurts to be optimistic.
