Once the two bolts were removed, it was a matter of carefully pulling the electrolytic capacitor can out and away from the chassis.
Here's how it looked:

Someone had cut all but one of the wires, and had wired individual electrolytics under the chassis. I am going to stuff new electrolytics inside the original can, using new wires.
First, the original guts had to be removed. I unfolded two of the four tiny tabs holding the cover in place, and set it aside. Here's what I found inside:

I was able to easily pry the old unit out of the can.
Next, I prepared four new electrolytics to go inside the can:

I added new wires to the four positive ends. All of the negative ends are connected to B- so all of the negative leads were twisted together and soldered to a black wire.

I then used some thick paper to make a new insulator to go inside the can, to help prevent anything from touching the chassis. I also taped up the exposed negative wires with electrical tape, so it should be fine.
The rebuilt can:

and how it looks mounted back on the radio - just like it did originally.

Edit: This job turned out to be much easier than I thought it would be. It was no big deal to remove the two bolts holding the speaker and to move the speaker aside enough to get to the other bolt holding the electrolytic can in place.
