If I fail then we can learn from it and try again.
It uses some of the OEM mounting points, however the added mounting points can be wherever you feel would be enough to support the lip. There isn't a whole lot of square footage on the bottom of the front bumper to work with, so it shouldn't be hard to choose some additional holes to drill for extra mounting points.
