Erik, if it helps, here are some pictures and a drawing. They explain it better than I did, which wasn't very good. The tanks missing the mud flap make it easier to see how the flat track guard sticks further forward, has a slight slant downward, and then the mud guard falls at a sharp drop.

Oh, if they're going to redo the upper hull molds, they should fix the slanted rear deck and enlarge the brake exhaust port armor cover (cylinder on driver's side next to jack block...I used 1/2" half-round styrene and seemed to come out about right). For the rear deck, keep the forward portion at the original height, the rear edge should be 3-mm lower; keep the side louvers horizontal with the top of the boxes following the sloped rear hull; trim the back plate accordingly.

Overall, the quality is definitely headed in the right direction.
