How to keep hubcaps on?

Hubcaps or Wheel covers?
I never had a problem with the dog dish style hubcaps,
but did loose a wheel cover a couple times.

Hubcaps on the light blue 1965,
wheel covers on the dark gray '64.

Its quite common for a full wheel cover to be called a hub cap.
Run away wheel covers were very common in the early to mid 70s. Radial tires were to blame.
I've got a set of those fancy but heavy wheel covers from a B-body that I would like to use but until I can find a way to keep them on the car....
I've also got a set of the retainers from a 87 Fifthe Ave spoke hub caps.
Haven't figuerd out how to morph these together yet.
If one of these monsters was to get away it might total loss one of todays vehicles. LOL
