I havent got mine yet, but i think they're going to a problem to mount with his mounting method.
The chassis rails i used (from Joe) arent quite the same height as the stock ones, they're a fraction taller. I had to grind my fuel tank mounts to fit them. If the mount for the boxes is the same, they may not fit.
And, with the C clamp style he's used, they will be in the way for mounting the headache rack. They'll raise it by several mm, which will put it past the top of the roof of the sleeper.
