There's nothing sticking out so trying to cut a head and screw it out is off the cards. Guess it's a local garage best quote I've had is £20 to remove the pair which I think it will be as the Mrs will murder me if I go buy a decent drill and the right bits to do the job. Replacing the bracket would cost a fair bit more about £35 for a second hand one or £65 new (it's a pretty large part that holds both sides boards and other things)
