bracket for bullet caps

I have a 62 caddy with a hub centric wheel and I want to run faux spider cap setup, I have the bullet lugs ,but no way to keep the caps on.I need a bracket setup or some pictures of other peoples brackets .the caps I am looking at have an all thread rod in the center already to go

 

You need advice...and i need pictures. late 70's GM fullsize cars had heavy spoke wheel covers. they had a bracket that bolted on 3 lugs and had a threaded nut in the center and were 5 on 5 bolt pattern. would fit the lac

 

The brackets like mentioned above were used on cars well into the nineties. My bro's Buick used them to hold the fake wires on.

 

These are the ones from my 90 Fleetwood, 3/8" threaded center, 5 on 5 bolt pattern.
