Barracuda Air Cleaner ?

I have 2 of the same air-cleaners,for my 67 B-Cuda coupe. They both have the Commando decals on them. Are you in Cali ??, Mine do not have the fitting on them for the hose to the oil filler cap. They are like Cavemans. Maybe the hose is early polution control,from Cali. I thought that did not start till 1968. Just a thuoght. Yours does look like a 273 4-bbl air-cleaner tho.
I wuould post picks of mine but I am having no luck at it.
