Air cleaner for a 1974 Swinger, 318 2bbl.

One day and I already love this forum. You guys are great.
I’m not aware of 2bbl dual snorkel air cleaners existing but then you can fill a warehouse full of stuff I don’t know.

Check out this website for more info:

Perhaps your 318 has been upgraded to a 4bbl already? The opening at the base of the air cleaner is larger on a 4bbl so it’s not ‘easy’ to just rest a 4bbl cleaner on top of a 2bbl carb.
I did contact Nick. He said it's def not original and also said what others did about someone adding a 2nd snorkel to the 2bbl air cleaner. He also sent a pic of what an original looks like.
