The 1-ton or 3800 had a 137" wheelbase and came with a 9' pickup box. The inside measurement is 108.125". A 3/4ton or longbed pickup has a 125.25" wheelbase and an 87" inside length.

If you have duals, I would assume you would have to remove them and possibly cut the inside of the box to fit the narrower singles. Someone else may know.

I don't think you can buy a 9' box. Perhaps weld 2 together?
