Integrity window from around 2002 need new crank
Your existing operator has the older style "rectangular" shaped body. That said, we'd like for you to take a look at the 39-171 operator that offers a newer rounder style. I believe the body will fit your window, but I am not 100% sure of the link arm. Look over the measurements and specifications to see if this could fit your window.
If your link arm is only 4-1/2" long, you'll have to reuse it. This can be done by drilling out the new and old arms, then installing the old arm on the new operator using our 62-014 rivet. To install this rivet, you'll have to hammer it in; I recommend doing it over a metal plate, if you have one. Let me know if you have any questions on this project.
