Are you asking about hubcaps or wheel covers ?   Chrysler had both and so did Plymouth and as long as the wheel centre has clips, the hub caps will fit.  As for the wheel covers, both cars used 15 inch wheels so they will fit also.

I know what your thinking, but Im driving the car daily until winter and Id hate to see my Mopar hubcaps stolen because I wasnt around. So I found a set of Chrysler hubcaps and they are cheap and Id rather have them on now until I redo the car.

So will they fit?
