This is a 46 (47) one one ton dually
I bought 6 7' bumpers from the salvage yard that were removed from step vans.
The profile and width is almost the same as the factory front bumper.
I wanted to match the as close as pictures that show original models which included rounded corners.
I used the factory dimensions for the length and width basis,so what I did was cut the rounded corners off of two bumpers to get the center runs and then welded those after extending them another 10" to the front and rear runs.
I will weld box steel from left to right as cross members to lay the floor on.The floor will be 2x6 pressure treated planks bolted down through the box steel runners with carriage bolts.
The stake sides are available in metal for $100 something per section,so I am looking at two per side and two across the back.
In the pictures they show the front as being formed curved steel for.
To me it looks exactly like the profile of a 55 gallon drum,so that is what I will use if I can form them enough to fit.
I have not got that far yet.
