The ventilation grille is mounted in the front panel using black mounting hardware, including sheet metal screws known as "parkers", plastic washers to protect the paintwork, and snap-on nuts that slide around the sheet metal in the front panel.
The plastic washers, which ensure that the paintwork is not damaged when the screws are tightened, were not used by Volkswagen in the early days. After noticing that the grill around the sheet metal screws was beginning to rust prematurely, Volkswagen modified these washers. When the VW Bus went to the dealer for servicing, this modification was carried out as an additional service. Unfortunately, it is not known when Volkswagen introduced this modification at the factory.
This assembly kit includes all the parts identical to the original, with the plastic rings added in case your VW Bus was not equipped with them at the factory.
