Even with the included mounting bracket, the screw holes do not line up with the mount on the vehicle. As the tow package is OEM, advertising that this is an 'exact' fit for my vehicle is false. In addition, even if the holes lined up, the included bolts are 5/8" too short. I had bought longer bolts before realizing that the holes didn't line up. I am very dissatisfied with this blatantly false advertising.

Bottom Line not recommended
