The gears on my cranks on some of my windows are worn out. Need new crank/operators.
The plate for the operator says "Truth"
Small control arm has # 20755

You could start with our 39-155 and 39-156. However, this is just an educated guess. I highly recommend going over our dimensions to confirm that everything matches up with your own operators.
