On my 91 they are plain Jane plastic covers that pop-off. When I painted the wheels they turned out nice.

But on a 420 SEL that I originally tried to buy, they have been updated or the car had some factory option. I've attached a pic to show what I saw. The wheel sets themselves were the same as I have now.

Basically I am looking to update from these plastic ones. But I do not know if they are pretty much universal or if there is a specific part number/series I should look at getting these from.

Thanks.
