The links I posted are from the 1929 to 1942 Chevrolet parts manual. What you see is the year(s) the part fits, the body style they fit, part identification, number required, and price for each part (1942 prices).
The other link is from the front of the book, it's listing the series number, wheelbase, type of vehicle, and description of said vehicle.
Right under the two colorful arrows at the bottom of each page linked, you will find the contents page and illustration pages. These are very handy for looking up parts and pictures of parts and item break downs.
