I just brought home my fathers old 38 1-1/2 ton truck. The original bed was replaced at some point with one that was pilfered from a newer wrecked Ford truck. Besides being much longer than the original, all the wood is rotted out. I would like to replace it with something resembling the original but I have only found a few pictures on the internet which do not provide me with much detail. If anyone can provide me with pictures, dimensions, material info, etc., I would be very appreciative. Leads to a restorable bed would be even better. I am also think of shortening the frame to match the short wheelbase model. Not only would it be more “cute”, it would seem more drivable and, most importantly, would fit in my garage. Does anyone have any experience or thought regarding this modification? Other than the driveshaft, it appears straightforward to me.
It is often easier to take a piece of frame from the middle, that way all the suspension pieces can remain intact, many rear frames also taper toward the rear, which would also remain intact. Find a straight section of frame, usually from just behind the cab, measure carefully, make marks on the remaining section to get good dimensions on. There are many splicing methods, find one you like that is tapered at the ends so it doesn't promote frame cracking.
Most beds were made by others, so copy one with the dimensions you like copied from others frames.
Good luck.

Nice truck! I like the picture with the dozer on the back. For shortening the frame, like ED said, find a straight section behind the cab, between 2 x-menber. Measure twice and cut once.... A comment way is to but weld the frame, than "fish plate" over the welded area with the cut section of the frame (if long enough) cutting the upper part of the C to create a L and welding it over. Frame welding is not for everyone, propper V notch, root pass and good weld is a must. Fish plate can be welded around and through some drilled holes. Just an idea that works for us... J.F.
I shortened (and Narrowed) my bed. It was a full size stake bed truck when I purchased it. Dont really haul anything with it but it does look good and also fit in my garage.
