During the 80's I never knew of any GM mechanic's time based on a Chilton"s manual.
No, it was the other way around. Chilton times were based on GM information.
Not sure how you got that confused to require your explanation.
I am not confused at all. I think I posted a pretty clear explanation of warranty times vs. book times and while you may understand the difference perhaps others didn't.
