two ways to do it!!!ONE remove green bond screw and remove the connector bar accross top between bot neutral busses.thenjust run a bond wire or a you can get a bonding term that goes under a screw on ground bar and to box.then move all grounds to left side buss bar.or leave as is and remove green ground screw and add a ground bar to box at screw holes in top pic on left side.move service ground wire(the one with the service wires)and connect it to new ground buss along with all ground wires.
