Specific 273-2bbl air cleaner

Please, I need at least one air cleaner (or even just the base plate) just like this one:





It was factory equipment on 273 2-barrel engines in Barracudas, 1966 to 1967. The lid is about 11" diameter, and the carb hole in the middle of the base plate is 2-5/8" diameter (please check this carefully; there's an almost identical-looking Slant-6 1bbl air cleaner with a carb hole that's 2-1/8" diameter).

The one I need is (obviously) not the same as the other kind of 273-2bbl air cleaner with the larger diameter and the snorkel:



Can anyone help, please? Thanks!
