Chevrolet usually published a book for the dealer of special bodies for Chevrolet trucks or as my 35 book is called special equipment for Chevrolet trucks. Some special bodies were installed at the Dealers, some if for a major fleet buyer installed at the factory or the chassis was shipped to the body builder for their installation. I had a 1949 3///4 ton with a dealer installed National dump hoist which used the factory pickup box.
