The metal attachment fell off my windshield taking of course the whole mirror assembly.....I pulled off the metal attachment piece....It has a plastic covering over the metal which attaches to the windshield.....My question is: what do I use to put it back on the window?.....What kind of adhesive?.....Or do I need an other mirror?.....Any help will be most appreciative.....My name is Bruce L. Hansen......Senior Citizen.....And I don't suffer fools.
