I'm guessing your asking about the "Autolite Parts" sticker seen on most Fords of the era. Not on a Pantera, and no "351" displacement sticker on the top cover either.
My research shows there are no decals anywhere on a "Pre-L" Pantera air cleaner. Later models, I'm not so sure. I would be very interested if anyone has evidence to the contrary. What year is your car?
