I've drilled holes in the base for the leads of the new capacitors and for a common ground conection
Here you can see the shapes by each terminal lug identifying each individual capacitor value.
Back on the bench, the new capacitors are inserted and their leads soldered to the base terminals.
The negative leads are twisted together; a wire will connect them to a ground terminal nearby.
The can halves are mated and a layer of Aluminum tape holds it all together.
