As far as I know, the pancake air cleaner was part of the "appearance" chrome package. Could have been a different air cleaner assembly offered. That car was sold in Birmingham MI and looks original.
The heavy duty air cleaner was an option from what I seen in the list. Could have been a different, larger or thicker element.
Who knows...
