Just downloaded this shop manual that's supposed to cover my 65 C10 (as well as other years).

Description clearly states it covers these trucks. But after I spent $20 and waited about an hour for a download, what I ended up with was a

"1966 Chevrolet Truck Manual Supplement"

From the manual "This supplement has been prepared for use with the 1963 Truck Shop Manual and covers service information particular to the 1966 truck"

I wrote and asked for an explanation and am waiting a reply. Most of the information describes work on a Chevy Van.
