Crank for a window box with broken tabs

A home owner from Arizona says:
A single vent window box installed in 1988, the window crank still works but the brackets for the screws have broken off. No markings or numbers on the part or on the window.

Hey thanks for contacting us. You might want to think about our 39-346 Jalousie Operator Replacement Kit. How does that match up? We don't have an arm that long, but you should be able to reuse it. Let me know what you think.
