Duster decal

Hi everyone, quick question... Dodge has the scat pack decals for the windows from the factory or dealer or maybe after joining the club but what about the Duster?
Did the dust cloud decals i see on ebay come on new Dusters? if anyone has any info or original pics of these decals I would like to see them.
I have never seen them on an original non-restored Duster, wondering if these ever existed or was it just a novelty to put the dust cloud decal on the glass... thanks Rich
