Hi John,
Pull the dizzy and see what you got. Size can vary, as can the diameter of the hole. Then head off to your local hardware store and see what they have that slips inside one another. Then buy the correct drill bit for the biggest one.
Go home, drill/enlarge the hole if needed, install. You could just add another hole and retain the current one, too.
Then drive on down to Monterey! Looking forward to seeing you there - I've arranged a special dancer for you at the Concorso.
