Interesting as I was thinking about this just yesterday too..
I believe the last word from J.M. was the General said no-go as some kind of worries about lawsuits...made no sense considering the way PHS and GM Canada seem to have no known real problems w/ it???.
And not what J.M. relayed but I've heard before there's supposed to a few train boxcars full of the build paperwork and would be a BIG project to fomat into a searchable format?.
GM Canada has theirs on microfilm and I wouldn't be surprised if GM-US really has theirs saved in this same format too?.
Does John Z perhaps have any wisdom on this that he can maybe comment on?.
I still have some copies of the GM Canada microfilm and it looks very similar to the GM Engineering info that Z-16 Dave had/has posted on his site?.
