I have this original 1956 Chevy dual quad "Batwing" air cleaner listed on Ebay starting at $9.99 with NO RESERVE. The auction ends tonight at 7PM Pacific Time. I know this is not a Supercar part but it is super rare and I thought many members would appreciate it. Free shipping to paid members in the US and $50 off international shipping for paid members.
Here is a link to the auction:
