Norge pannier retaining brackets

I would like to remove the two brackets that the pawls at the front of the panniers clip to on my Norge. These are mounted adjacent to the pillion footrests, and I want to clean up the metal and paint them. One of the retaining screws on each of the brackets has a seriously waisted section on its head though, and I’m sure it would shear if I applied the necessary force to loosen it. In fact it looks like they were designed to break if an attemp is made to remove them. I would appreciate the advice of anyone who has had these parts off.Many thankBrian
