Dodge D60 L5 cargo bed

[gustavo]

Good morning to everybody, I am going to restore this Dodge D60 L5 and I am facing some troubles to understand how was originally this cargo bed: it seems it was shortened in the front section to allow the dumping, as well as in the rear section for the unloading operations. All what I found is a picture of the side coming from a Italian Army manual, but I have no idea on how was the rear. Does someone know how it looked the rear cross section? I suspect it was tapered, of course I am not sure.
Thank you in advance for your support.
