Air cleaner for a 1974 Swinger, 318 2bbl.

That appears to be a 2-barrel air cleaner to which someone added a second snorkel. The diameter is too small for a factory four-barrel air cleaner, the lid looks like a two-barrel stamping, and the scale between the air cleaner body and snorkels is goofy.

Here's an original four-barrel dual-snorkel for comparison. Look at the difference in distance between the raised ring for the filter element between it and the one on the car.

Either way, I'll take a look next trip to my storage area, but I don't think my Challenger came with an air cleaner.
