I finally installed my hitch today. I had to modify it a bit to accommodate my Kuat rack. Also had problems with the carriage bolts not fitting through the frame holes. Just grind off a little on each side and they go right through.
I needed a hitch that would work with a 2" receiver and since they don't make a class III for a focus I made my own.
I then powder coated it the same color as the car.
Installed and works great!
