Hi Mark,
I'm not sure what diameter those elements are, but one option might be these 'snap bushings' made by Heyco.
NPA is their distributor in Adelaide

In the past, I've used these for both 2m and 23cm yagis. I use a small amount of epoxy glue to secure the element once I'm happy that it's centered. No need for those retaining rings.
I've also bought Delrin insulators from Directive Systems, and I note that they list them (and the keepers) for both 3/16-inch and 1/4-inch elements.
I'm using the 3/16-inch insulators on my 70cm yagis.
Hope this helps.
