I have a 280ZX AFM listed for sale on Craigslist right now... search "Datsun 280ZX Air Flow Meter" under the location Skagit, WA...AFM is labeled "A31 622 420"...my research indicated that it was used in the 79-83 year model ZX's...you'd have to research whether it's applicable to the turbo ZX or not...I don't know.
