Just an update... I had been looking for the 14mm hex for a couple days now. I checked Sears Hardware, Home Depot, Lowes. None had it.
I had to stop in AutoZone and they had just gotten in a shipment of tools. They have a 3 pack of hex sockets from a company called OEM. The sizes are 12mm, 14mm and 17mm. They are 1/2" drive and cost $7.99. The part number on the package is 25417 and the sku is 076812254177
I hope this helps anyone who needs the socket in the future.
