FA-9 Flash Bracket Adapter ($28.00)  

The FA-9 slides onto the swinging arm of the Wimberley Head Version II (WH-200) and allows you to use the old-style Wimberley Head flashbracket (F-4). The FA-9 has special cutouts that allow it to spring open and stay attached to the arm of the head even when you are not using a flash bracket.
