I'm pretty sure they all had them Dave & porschetub, but were often lost & never replaced if broken or taken off for a repaint or detailing, etc.
Mine were taken off by the dealer who had repainted it when new at customer request, but were never put back on until I did so after 3 years in `75/76.
They were there as a finish piece & held the round foam "air filter" of questionable worth in that purpose, for the flow thru ventilation.
Cheers!
