I have managed to source finally a set of Champion spark plug caps, but need to find the rubber sleeves.
Holden only has sleeves for the distributor cap (they are different).
I was thinking of these:

(just the rubber, the rest could be scrapped).
But maybe someone has a better solution? Some motorcycle parts?
