When I brought my 2003 VS from the original owner it was missing a few gaskets where things (grill, hood trim, door handles, etc.) we’re mounted to the body.
I am a firm believer that anywhere something is mounted to a painted body surface there should be a barrier (a.k.a. gasket). It doesn’t seal a darned thing with the grill but it keeps the paint from chipping at the edges.
I seem to recall buying all the rubber bits I needed from Kirk and Mary before they sold the business. I imagine they aren’t too terribly hard to find if you look in the right places: Vintage Motorcars or Special Edition.
