you can also use the top of the frame rail rather than the side rail. We used a piece of 3/8" aluminum angle and drilled holes for top mounting and then on the long leg of the angle drilled the mounting hole for the ball on an old 68 Coronet some 30 years ago. We cut and shaped it to where it looked like a part not a piece of angle. It looked nice and not out of place.
