Its really fiddley. Keep at it. If u stripped out the threads, tap it, or file off The flange and jb weld a nut to the back side. I only remember that it was very cramped quarters under there and with a wrench i could only get like an 1/8 of a turn before i had to reposition the wrench. I doubt ur gonna find the bracket (maybe EBAY) Or u may have to re engineer it. Best of luck. Having working brake lights is cool!
