Thanks for reaching out! Take a look at the 39-020 and 39-021 operators along with the 39-520 track. I believe these should work on your windows.

I've included a guide for instructions on how to install a wood casement window crank operator. Keep in mind you may need to drill new installation holes.

Thank you so much!! We are going to confirm the lengths are correct but it looks like a match to me!
