RARE experimental air cleaner 62' for 383 or 413 dual inline 4 barrels

Don't mean to post in the ad again, but I pretty sure Fram took Chryslers blueprints and made some of the Mopar air cleaners too, then supplied them to Chrysler, I know this was done with the 426 Hemi and Air Grabber ones in 69-71. Maybe Fram made this air cleaner as well? Very cool :glasses7:
