I just did this mod, but did not remove as much material.
It allows the hood to tuck further up under the back, but for mine, it does not stick quite so far straight back.
Basically this cut, but without removing as much material.
It's much better than factory, and it only took cutting the tab flush with the plastic & trimming the edges of the screw mounts.
The whole thing fits much better.
Oh, I didn't mod the running board at all, they still fit in the "down" position as listed in the original instructions.
It's kind of a shame they didn't use the transform from the deluxe. I must admit, I like that version a lot better.
