Hi, I'm new to the forum. I have a 1965 442 that is missing the air cleaner. Is the 66 air cleaner different? It seems that the snorkel is on the drivers side rather than the passenger side in 66. Also does the 66 lack the breather on the snorkel?

Thanks for the help!

 

Welcome. The 1965 cars used the Rochester 4GC carb with the small air horn. The 1966-up cars use the Qjet with the large air horn. A 1966 air cleaner won't fit on a 1965 carb (at least not without an adapter ring).
