There is an air cleaner on ebay now listed as an original 74 pantera item. 170301970644 I do not think it is an original 1974 Pantera air cleaner... or a 1972 or 1973 original 1974 Pantera air cleaner. It may not be an original Pantera air cleaner at all. I can't say if it is early 1971 because I don't have good photos of that one yet. Barry
