Thanks for reaching out! Your window crank reminds me of the 39-031 EntryGard Dual Arm Operator. You'll need to carefully look over the dimensions and compare them to confirm it is the right replacement.

You'll find the opposite handed version along with a few of the compatible hardware parts and accessories tagged below.
