Take a look at our 39-188, this looks like it could be a good match. The link arm is 5", rather than 4-1/2", but it may still work. If you install it and find the window does not open and close properly, you can swap the link arms out. You would drill them off the old and new operators, then install the only link arm on the new operator using a 62-014 rivet.
