The shorty curved edge opening with no snorkle or flapper (in the noted ebay auction) is odd
Steve,
That is where the snorkel was originally located. A block off plate was added (to cover the hole) when DT (Ford?) moved the snorkel to the opposite side of the air cleaner. The heat activated vacuum flapper was still used, as it was part of the snorkel. The early ('71) air cleaners did not have the other vacuum valve that is on the air cleaner in the eBay auction.
