Replacement air cleaner

My 66 Valiant has a Carter BBS that is missing the bail. So I don't have a way to secure an air cleaner to the carburetor. Anybody have a bail for sale? Or what are people using as an air cleaner assembly that have the same problem as me. I thought maybe a clamp on VW type, but all I find are for a 2 inch inlet. BBS are roughly 2.5 inches. So those seem to be out of consideration.
Any ideas people?
