Crank housing unit replacement

The crank gears are sheared off of these window units. Can you help me identify the right part for the whole housing unit and the crank?

Hi there!

Based on what I see here, my recommendation would be the 39-221B operator. Compare our dimensions with yours to see if this matches up with your old assembly.

That looks like it! Is there an associated crank that goes with these?
