I didn't drill holes. The Grimmspeed bracket uses the tow hook port and allows a lot of adjustability. If Ohio does away with the front plate requirement, it all can disappear without a trace. And, if you are so inclined, you can remove the plate and bracket entirely for a car meet, replace the port cover, and it's back to new again.
