Hi Ray,
The license plate should mount in the middle of the bumper. Here's a pic of mine. pic of rear of truck
here's another angle of the bracket with license plate. pic#2

I had to mount 1 of the holes into the back of the bed, and 2 others in the bottom of the bumper.
The license plate bracket can be found at most of the truck vendors. smile

My truck don't leak oil, it just marks its teritory.
