Durango Gold and the License Plate Holder

This is gonna sound strange.  When you buy your rig, normally the deal may install your plates.  KZ provides this plastic plate hanger on the back of the right rear light.  The light is "sealed" to the fiberglass meaning you cannot remove the lense w/o damaging either the light or the fiberglass.  If you were to zoom in closely, it appears as though someone from either KZ or the dealer "attempted" to remove and gouged the surface.  So I am stuck with this condition.  How am I to mount my license plate to this?  You cannot bend the plastic sufficiently to put use wrench from the head yet the plastic cannot support the torque and load of a locknut.  You also do not want a head protruding and marring the surface.  I would go back to the dealer but the they mucked up so much already on this that I am better off just taking care of things myself at this point.   I may be better off using a dremmel and cutting this off and installing some sort of mounting kit on the receiving hitch bar....  Would like some ideas as I've already exhausted mine.
