My 46 had a wooden dump grain bed on it, sounds similar to yours. I think they are pretty neat, the craftsmanship was great on mine, they dont make things like that anymore...
Mine works good and just needs a clean up and fresh wood and paint, I think they make a neat addition to these old trucks and I'm sure will come in hand one day. Just need to decide what kind of wood to use.

Only bad part about mine is the controls are huge metal levers coming up from the floor, taking away some of the already limited cab space.
