Original Metal Center Caps can be restored by polishing the chrome with 0000 steel wool, but if the centers are foggy, they have to be replaced. Fortunately, replacements became available in 2021 for ~$16/set.

Replacement cap assemblies are plastic, and are supplied with common screws instead of the specially-shaped original screws.
