That particular style of snorkel end looks more like 1967 than 1969, to me. 1969 air cleaners usually had a rubber hose going to one snorkel (held to the outer rh section of the air cleaner) for the interim evaporative emissions system (that put the fuel vapors inside of the crankcase for storage, until the engine was started).
As I recall, 1966 & 1967 had that flared end snorkel. 1968 had a different insert that was smoother, like an "insert" rather than just flared metal. 1969 went to the rectangular snorkel, as the 1970-71 air cleaners had.
Just some thoughts,
