Just a dumb question here - I want to replace the chrome trim rings on a 90 Plymouth Grand Voyager, with the screw-on hubcaps. Do I have to find specific rings for the wheels, or are generic rings workable?
The main thing is to find the right depth. Measure the depth of the factory ring. You probably can't use one that is deeper, but one that is the same depth or shallower should fit fine.
Rings designed for a RWD car will probably be too deep.
