I would probably replace the electrolytic caps with modern, low ESR ones as a matter of course. They are most likely dried out after all those years and could cause the PSU to malfunction under load. I strongly suggest checking them with an ESR meter at least.

If you want to keep the stock look, you can always gut the original cans and put a modern capacitor inside. They will certainly be smaller than those period monsters.
