Thanks, Mike!
Not much progress the past two days. Yesterday, I removed the cover from one of the electrolytics:

I had to use a heat gun to melt the tar underneath, which held this cover in place, until it softened enough to allow removal.
I also have a 53-960 parts chassis; one of its electrolytics also has a cover over it like this. Using the same technique, I also removed that cover. My plan is to use these to cover both electrolytics once rebuilt.
Today, I tried to mask off the area surrounding both electrolytic cans. Then, using a cutter wheel on my Ryobi "Dremel" tool, I cut the tops of both cans off:

Despite my attempt at masking off the surrounding area, some aluminum dust still managed to get through the tape and paper towel. I used a can of compressed air to spray air over the entire area, top and bottom. I hope I was able to get all of it off (and out of) the radio chassis.
The next step was to drill holes in the bases of the old electrolytic cans for the leads of the new electrolytics:

The holes were drilled from the bottom, so the positive leads will be going right against the proper solder terminals on the base of the old electrolytic cans.
I forgot that the two 10 uF sections are connected in parallel in the electrolytic to the left in the photo above - so I drilled one hole that was not needed. That's OK. I will be using a single 22 uF to replace those two 10 uF sections.
Nothing else to do now but wait for the new electrolytics.
