Restagraf 218 is documented as a compatible aftermarket fastener, not as proof that Restagraf supplied Porsche production. It is sold as a bag of 50 while the PET quantity depends on the installation. Confirm the 7-7.2 mm panel opening, 0.5-3 mm panel thickness, 4.8 mm screw and required quantity before ordering.
