There are different methods for replacing electrolytics and they don't all amount to restuffing. My recapping article (
http://antiqueradio.org/recap.htm) has links to articles that illustrate various ways to skin the cat.
In my CTC-7 article is an explanation of how I left the original can bases intact and mounted the new electrolytics on them, as shown here:
Basically, you saw off the old can, drill little holes next to each terminal, slide the new cap leads down through the holes, and connect them up. If you don't care how the TV looks, you can stop there.
If you care about original appearance, you can pull the innards out of the old cans and epoxy them back on to enclose the new caps. In this case, I recommend that you leave the cans off until you have finished your restoration and you know that you won't need to change any power-supply wiring (or even read the values on the new caps to assure yourself that you didn't install a wrong value).
