Hello Philip.

I have the "1954 CHEVROLET TRUCK WIRING DIAGRAMS FOR COMPLETE CHASSIS" but I do not know where I bought it. It has 4 interior pages and a glossy cardboard front and back cover. Black print on inside and red print on outside. A total of ten pages of useful information and drawings. It has specifications and wiring/installation diagrams for all electrical circuits and components (standard and optional). The print is clear and readable (I need my reading glasses for only one page). It is a licensed reprint of selected pages from Chevrolet service publications (not photocopies).

I cannot find this listed in a Chevy Duty catalog (mine is #25) and cannot find it on their website (their search engine does not work for "wiring diagram" - it gives errors for pages 2-8). So, I cannot confirm that this is kind of book they sell.
