Does anyone know the correct air filter part number for a 66 442 original air cleaner?

Should be A90CW. Manual or auto?

The 1966 Oldsmobile Parts Catalog shows two possibilities for the 442 under group 3.410 (air cleaner element):
If the quadrajet, part number 6421746
If the Tri-carb, part number 6420700

Did manual (open element) applications use the same filter element as automatic (closed element) applications in '66-7?

Only one was in the parts catalog for the 4BBL. It didn't distinguish between manual or automatic transmissions.

The Tri-Carb number you show 6420700 doesn't show up in any of my parts info starting in 1972... 6422468 (A220C) is the most current that I show for the Tri-Carb setup...

Perhaps the part number changed after 1966.(?)
