Hello,

We'd be happy to look into this for you but we would also need to see the rest of the link arm that attaches the crank to the window linkage. If you could write out the exact distance between the installation holes, as well as measure the diameter of the hole at the end of the link arm, that would also help us narrow down your options. In the meantime, you're welcome to look through our selection here. Thank you! 

A home owner from Brooklyn NY says:
Attached are pictures of link arm and installation holes. The link arm hole size is3/8 inches. There are 3 installation holes. Two on bottom not parallel to one another and one on top not exactly in line with either bottom hole.
The hole most in line with the top is 4.5 inches away. The other bottom hole is 5.25 inches from top

Thanks for getting back to us. Your operator resembles the 39-259 shown below. We also offer the 39-258 opposite-handed version. Take a look and let us know if you notice any discrepancies.

It looks like a very good match. I would also need a couple of plastic 3/8 diameter circular pieces to help hold it in place. How do I place this order and how long for delivery? Should I order through the phone number?
