There are three different air cleaners; L48 manual, L48 automatic (has manifold heat tube neck on snout), and one for everything else (L34/35, L78, Z/28). There are also two different heights of extension rings (one for L48 and one for all others), and two different air cleaner studs that match up with the extension ring usages. You'll have to take some measurements from the top of your carb to a fixed point (like to a piece of wood laid across the fenders) and compare it to some other cars with ZL2 to see which combination will work for you and will actually seal to the hood.
