I ordered a set of 4! These caps fit like a dream! Masterfully packaged and arrived faster than expected which is amazing! You should already have the correct steel wheels for installation. Make sure the valve stem is aligned with the hub cap before securing the hub cap with the jam nuts. super easy! I recommend them if you really want your car to look like a real Chrysler! Enjoy shopping! Update: Almost a year later these cases are still standing and looking brand new! LOVE!
