Up for sale is a datsun 240z air fitter box, this would have come on 1971, 1972, 1973 cars. Or you can run it on any Z that you are running round top SU carbs. This housing was sand blasted primed and painted. the seals were also replaced.  i got the color matched at a paint store so you wont find a better match. If you have any questions feel free to ask. Happy Bidding!
