WOW! I have never seen a 5 window cab for these years. If I am correct according to my factory assembly manual. The 1 ton and larger cabs are not the same. On 1 ton and larger cabs there is a wheel well on the step plate inside the cab. Although, if you can find one you might be able to section the back panel on to a regular cab. I would defiantly check it out first. Also if you are planning any type of total retro then I highly recommend buying the 1955 to 1959 Chevy truck assembly manual. It's a great resource for not only you tear down & re-assembly but it's great for finding what those missing parts look like and go.
