parimus,
i dun think the nut came from the interior, the one you shown in the photo looks alike a heavy duty/anti vibration nut..maybe from your front lip
i checked already...yeah...it's exactly the type of nut from the exhaust manifold but all of the nuts are still intact...i wonder where it is from......anyway thanks bro hattech-v, that's very helpful of you...
You know those progressive springs where the closer part coils always knocks each another when you're going through potholes, how to protect them from scratching till they rust? rubber water hose? got ah so small...
