I've seen one on an 06A car.
My 06A has the fuel line clip, build date is June 18? and the shipping date is June 22 or 23?, if I remember correctly. Canadian Docs Z28. It says "Stamp Rite" on it, its black, not phospahate, never been off the fuel line.
No PCV clip, in fact NEVER seen one on a Z, just L78 as posted.
