To remove the bolt that held the long screw and black part in place,

use a small but long tool (nail or screwdriver) and put it in the hole, where the removed screw was previously, but not through the upper part of the frame, but diagonally from the outside - thus the bolt can be slightly pushed out of the frame

They can either be removed with a specific tool, or with a chisel and a hammer (possibly rubber hammer)

Check with paint shop if the wholes should be protected

If needed - insert (short) screws in all places, where there were any before, to save their guideway (14 small type screws, 7 bigger type)

And the frame is ready for a fresh new paint!!!
