It will not work with a calmini truss as it hangs down too far. I guess it will work with a dropped diff if you drop the back of the plate a little on the rear crossmember.
It looks like 3/16" plate, I will know for sure end of the week when I recieve mine.
They come unpainted too .
It will be going on my X-90 with the 2" calmini lft kit on it.
