Good to hear the clarification. I think we're all on the same page now.
As to the production documents, they were compiled and published in the '80s. They were retyped but the data was taken from original Chevrolet records that the author obtained with Chevrolet's permission.
I didn't mean to upset anyone with my answers, and if I did I apologize. I just thought the titles of the pages made it very clear as to the meaning of the data.
