wow, thats a crazy problem. Its hard to tell from those pictures exactly what has broken. If I was going to fix it, i'd jack up the suspension from the small gap you have, remove the tire, inspect the connection between the control arm (i think thats what its called, not looking at manual at the moment) and the brake drum assembly. if its broken metal on the control arm, that would need replacing and would require putting spring compressors or a good chain around the compressed spring, re-lowering of the control arm, then replacement of the control arm. if its just a bushing or a bolt that broke, once the pressure is off the connection, find a new bolt and put it in.
