Just keep spinning the nut/stud out ccw and then remove the red plastic cover. (Don't lose the 3 metal spacers in the cover) Then you can remove the nut from the stud. Re-install the stud with red loctite and re-assemble. The front stud holds the coil in place so you'll have to reset the clearance of the coil. If the stud is stripped you'll need a 6 x 1.00mm helicoil repair.
