Has anyone successfully used the USCartool A500 Crossmember?

Another thing I fixed this morning. When I first bolted their crossmember in, it wasn't level side to side. So spent some time filing out the bolt holes on the bottom side, and welding in material on the upper side., and vice versa on the other side. So now it sits level when bolted in. Wanted to get that fixed before I drill the new inner holes.
