the point is to give a material a quality of a person for example a mirror to be a reflective person, concrete a adaptable person, glass a introverted person.
I'm If it is a stock ford part try the ford dealer if it is an aftermarket then get the brand name and google it. Then there is always going to an auto salavage yard and hoping to find one in good shape.. Good luck!
USA Yes, proper grounding WILL help protect the house. That is what ground rods and bonding the metal water pipe are for - to dissipate non-system generated fault currents. Without getting into all the stuff behind what I just wrote, the more grounding, the better path the lightning current has to take to the ground where it can be dissipated. And the building ground and bonding system is supposed to be bonded to the lightning protection system ground. Vincent has a good answer. Follow his advice.
