Cluster is held on by friction. You will need one of those old type wire cloth hangers. Cut it into two 8-10 inch length pieces. Take a plier and bend the ends to form a half inch right angle bend. Insert and slide the bent end into either side of the cluster about 2/3 up from the bottom. Turn the wire 90 degrees so that the bent end's bend gets behind the cluster and pull. Its usually better to put another bend on the other side of the wire to let you know that you have turned it 90 degrees.
Hope this makes any sense lol
Or you can by the tool which cost like $40 or something
