Here is the light box installed (thumb tight only) You may notice my end support/mounting brackets on each side. I drilled the face to take square nylon set nuts. I am going to sleeve the mounting screws with rubber vacuum hose to provide some back pressure, and with this grill mounted soild to the Face at the center, these end mounts will not only stabilze the grill, but with the nylon nuts, and the rubber sleeves, give me 4 points of adjustment to (hopefully) ensure proper alignment with the head light doors. I mean it just would not do to have all this work, and not have my grill look as much like one piece as possible.
And a close up of the center junction where my wires all come out:
