Lots of custom work here ! Sounds like your bed is longer, wider, and higher than stock, plus will be tubbed for the duallys ? You can buy a reproduction tailgate for the '40, that has the Chevrolet script stamped into it, however, its not going to be wide enough, or high enough. Since you already have the sides fabbed, might as well go back and have him make the tailgate - its just roll formed top and bottom. You can buy a Chevrolet script decal if you want.
Boards are easiest part. Finding bed strips, and bed angle is going to be difficult. You could have something custom fabricated from stainless or aluminum I guess
