Anderson window crank cover broke

Our 1980 Anderson casement cover is cracked. When you crank it closed the gear screw comes out. I don't know if we need just a new cover or the whole arm assembly. Not sure if the crack is what's causing the problem or if the problem caused the crack.

If that gear screw is coming out, then you will need a new operator. If possible, please remove yours from the window and take a few pictures of it. That will help us find a good match. Please also provide your measurements.
