Just a thought, consider some loctite on the mounting screws for the lights when you put them on the car. I saw somewhere you can get a locking nut for driving lamps, like a regular nut, but with a setscrew in the side to lock it in place.
Also, might want to kick up the insurance coverage by another $1000.00 Fender benders could be tragic.
I'm guessing you have classic insurance, agreed value, Haggerty etc.
