I don't have it here now, but I do have a Resto Pack from Chevrolet for my 1950. Many of you have them. Re-prints of original Chevy documents, specs, engineering data, weights and dimensions, including drawings of truck cabs and bodies, etc. I remember drawings of stake beds, with and without side boards, available from Chevrolet for all the truck lines. Even if they were third party Chevy would have had design parameters they had to follow....
