Mounting both replica license plates in the stock locations means you are no longer legal. Some states require both front and rear state plates, so check your local laws if you are concerned about being illegal. Rear Plates are required in all states, and rear plates must be illuminated at night.
My jeep has a hitch, which adds another surface on the back of the jeep. The hitch is farther back than the stock jeep rear bumper plate (the piece that the bumperettes attach to). So the tube for the hitch would get in the way of seeing the plate from the rear if I mounted it to the rear bumper plate I had to mount to the hitch tube. I decided I didn’t want to just screw the plate into the hitch tube, as there would be very little support for the plate, and I thought it would get bent too easy.
To deal with this situation I came up with the following solution:
An all metal license plate frame (I got mine from O’Rielly’s for $10) mounted to the hitch tube. A set of “bolt lights” (I got mine from amazon $7). Since my jeep had a rear hitch, the trailer wiring was in place, so I tapped into the trailer harness for power for the bolt lights. I used a 2 pin trailer wire($3) to allow me to disconnect the lights if I have need to do so. Here’s what is looks like. The plate fit perfectly between the center hitch and the bumperette.
You can also see I got my vanity plate from Colorado, and there in the right side of the last shot is my garage “couch” made from the ripped/nasty rear seat I replaced.
Considering my plates, I did also pick up a pack of “security” license plate screws as well. The pack I picked up had long bolt style, short bolt style, the style that screws into plastic, the plastic tabs, and the special tool. So all three of my plates now have these special screws/bolts in them, just in case someone thinks they can get a quick souvenir.
