nice job. Attach underneath or just using the license plate holes? If you've got the supplies laying around....what about one the length of the bumper? Maybe as tall as the bumper? Just throwing idea's out there.
Can't remember if they still sell them or not. I'd say you could make some money on the side if you wanted.
At work we had a centrifuge go on the frits. Parts are no longer available. It has a 1/4 hp motor I can use for a small grinder/sander/polisher. The cool part is it has a functional electric lid latch. I might use that on the tail light fuel filler. I'll run a hard line release, under the bumper, in case it doesn't work electrically.
