I've not been anywheres this neat when I've restuffed cans. Or more precisely I've just hacksawed off the can just above the rubber insulator, while it's still on the chassis. And put one of the bigger replacements above chassis, and smaller ones tied to the terminals below chassis. That way, I don't have to unsolder the wiring under the chassis. Looks fairly ugly, though... I just think of the old cap's terminals as a terminal strip now.
