I had my gx 470 year 2003 front and rear differentials serviced today at 90k. During my inspection underneath the engine, I found missing screws on the plastic cover, 2 screws are missing out of 5. The sixth fastener is a plastic. The picture is taken under the engine, the screw to the left is the one holding the plastic cover, does anybody know the part number? The screw to the right is the fastener of the front bumper
