Here is the solution that we had come up with on the license plate mount in the rear. When being shown, there is a unit cover that affixes to the license plate. Still not absolutely legal because there is no light, but close enough. Make the kid sit all day long. Hopefully they don't go alphabetically. Good Luck!
You can run the CJ style hand brake, as long as you mount the handle to either a angle iron mounted under the dash to secure the handle to. I would be apprehensive to drill into the dash to mount, but it is your rig. Set it up how you want it, we will still admire your ride.
