Are you dead set that it has to be at the rear of the vehicle?
Any reason you can't attach it to the rear bar of the ROPS with some conduit clamps? (
McMaster-Carr )
I am waiting for my title to be sent to my local title bureau, then change the body classification and put car plates on mine using the clamps from McMaster. As dumb as it sounds, when mine was inspected, the paperwork made no mention of the license plate being illuminated at dark.
I currently have my little plate attached to my tailgate using the plastic push pins. I am a -5 not a -3 though.
