My 1998 Malibu has decorative plastic "wheel nut caps" that screw on
over the real lug nuts to keep the wheel covers in place. They are held
onto the wheel cover with flexible plastic tangs. Two of these wheel
nut caps are missing on one wheel causing the wheel cover to rattle
when going over bumps.
Can these nut caps be obtained from GM or any other source for a
reasonable price and without having to buy a complete set?
