Early unsilenced 2 barrel air cleaner

[coffeedart67]

I would like to use an early slant six air cleaner on my 273 2 barrel, did any early slant sixes come with a two barrel? I am talking about the unsilenced air cleaners, similar to the 273 4 barrel air cleaners. What years slant sixes had these air cleaners? I have a chrome mopar performance air cleaner that I have used the top and a bottom from 2 barrel snorkle air cleaner (sides cut off), but the mopar air cleaner looks to big to me.
Thanks

They made a 273 2bbl with an unsilenced air cleaner in '66 and '67. The first year for the 2bbl in a slant 6 was '77.
