Detours bumper is offset to the driver's side to allow about 1/2 of the rear window to remain unobstructed. With this design, and Mark's recommendation, you simply move the license plate over to the right, and use the upper and lower (2) screw in points. I think there's a bracket that can be used so you can tie in to the normal 4 points.



Eventually I made this...



I removed the other licence plate after this picture was taken.
