The 66 C5ZZ-9600-N air cleaner was a chrome top and Ford Corporate Blue base, and there was a connection for the crankcase breather in the base. Yours however, appears to be the cheap copy, not an original or good repro. A larger photo will help.
The 64-64 C5ZZ-9600-N had a gold base, and may or may not have the base connector. The chrome lid on the earlier version 64, early 65, had a very different "double ring" design.
