Hello, I am renovating a house down in Florida and am trying to make sure I get the correct parts for these window cranks which I would prefer to keep since they seem to work OK (though they have not been maintained). The link arm is 2 1/2" and the operator itself is 1 3/4" wide at the base and approximately 5" in height. My guess is that the Andersen operator (39-258) will be appropriate, but I also think I need some additional parts. The bar that runs along the bar of each window (the torque bar?) is not held in place in a few cases, since the pieces that do so have broken. I can certainly take more pictures if that would help you identify the correct parts for me to order. Thanks for your help.
Regards,
Clem
