Somehow I've managed to lose the retainer nut, 1/4 turn fastener and spacer for one of the rear corners of my under cover (engine splash cover on the bottom of the car). The only thing I can locate part number wise is the retainer nut which I think is right, -W716006-S439.
If anyone has the part numbers for the fastener and spacer I would be forever grateful.
TIA!
