I am looking for the attached crank assemblies. I have multiple windows where the swing arm is bent. It shows part number 30615 / 30894 on the assembly and part number 40397 on the swing arm.

Thanks for contacting us. I'm afraid we don't have an exact match for this operator. We do have the 39-089 and 39-090. These lack the gear arm offset and that bottom housing tab, but look them over and see if you could still get them to work regardless.
