SO After taking my side wing off to access door bracket that needs rewelding come across the bumper bracket that holds front bumper on that looks like this picture.

How are these held on are they bolted on as mine looks to be welded in place and totally rotten to the point if I unscrew the bolts I know its going to brake.
