Awning window handle sos

This is an old operator that is no longer made. I believe in the past I used the 39-056 operator. I had to remove the link arm and use a nut and bolt or possibly a groove pin like the 33-077 with an e-ring. Take note once the parts are altered they can not be returned. Plus it's been a while since I've done this repair so it may be a bit difficult for you.

How well does the window operate? If it's not working well, you might want to consider replacing the complete window.
