Dealer Service Door Jamb Tag

[gwp4]

Hi Camaro Experts -

Does anyone know if the dealer service door jamb tag (see attached photo) was installed on all 1968 Camaros?  Did all dealerships install these or were they only used by a small number?  I wanted to check to see if it would be factory incorrect for a 1968 Camaro not to have one on the driver's side door jamb.

Many thanks.  gwp4

As you stated, it's a dealer installed sticker. Never installed from the factory. And there's no way of knowing how many dealers used that particular sticker.
