Will this Anderesen Awning Operating Kit replace my existing broken one. The pivot arms are stamped F 7184A 11. The round bar attached to the window measures 6 15/16" long. This is a 24" high by 20" wide awning window.

I'm not sure. How do the specs we show match your hardware? Is the style the same? If you aren't sure, please take a few pictures of your existing operator and show us.
