Actually, I'm planning to cut away most of the bezels and just use the nicely curved "ring" parts, and add it to a fiberglass/epoxy (which, btw, is what the truck parts are) bezel that I'm preparing. You see, the holes for the 7" rounds are centered on the truck parts, and I want them to be over nearer the outer edge of the bezel, because I want to include not only 7" round hi/lo beams, but also 5", located inboard, hi beams as well as small but bright, yellow LED truck lights to serve as Daytime Running Lights (the LEDs won't use much power, and with their lifespan, can stay on without impacting on the lifespan of the H4 and H3 bulbs in the outer and inner headlights).

So you can see how complicated this will be.

Take care.
