Early 260 or 289 air cleaner. It has the correct notch underneath for the 4bbl carburetor to clear the choke. Includes lid and snorkel. It isn't heavily pitted but the paint is weathered and ugly.
Would look great with a coat of primer.
Please see photos for details.
Make sure to check the shipping rates for the best price - Ebay doesn't always show the cheapest option first.
Thanks for looking!
