From reading a lot of people's post I can tell that they are not understanding the geometry involved, and I just thought of a way to explain it to you.
Take a piece of paper That will represent a blade, hold that paper 90 deg. To the top of a table and then curve the paper, the cutting edge remains flat to the table, now take that curved piece of paper and slant it back on an angle and now you see it's no longer flat to the table. That is what will happen to any blade that does not have a flat area to mount too. On this box blade the (V) portion is not mounted crooked, both sides of the (V) are dished, and the result will be each pass you make in the dirt will be dished. So putting the blades on and trying to adjust them straight would be impossible because as soon as you suck those bolts tight you curve the blade, and from my example with the sheet of paper it's very easy to understand.
The box blade was never damaged in shipping because there was not a mark on it.
I think we all understand that. Just put the blades on loose, set it on a flat slab of concrete, tighten them down (yes, they will bow because of what you have described), and then look at the space between the concrete and the blades. If its bowed as you describe, it should rock side-to-side like two rocking horse rockers. If it bowed the opposite as you describe, it will sit on all four blade ends and be high in the middle. Either way, you won't know until you do it and see just how far it is actually off.
