Harley Davidson Panhead “BIRD” 7″ air cleaner and backing plate. Backing plate looks to be OEM Harley Davidson. No matter has all 4 J slot rivets clenched tight, none wobble. Cover has one J slot compromised, but as tight as this cover fits it will not be an issue. I can install cover on plate without serious difficulty, but need a flat driver to get it removed. Probably with some lubrication and when mounted can be twisted off, maybe? Will not be too shiny for your patina machine, but not trash either.
