"Chevrolet books" ? Don't know what publications they are. Title/date/author/source. Official GM document? I'm all ears.
1st picture is from the
"Chevrolet Truck Illustration and Special Information Catalog effective October 1, 1966".
The 2nd picture is from the
"Truck Data Book Specifications Catalog for Chevrolet Salesmen February 20, 1958".
