Hello, thank you for posting,

Your window either uses the 39-253RB and 39-253LB that uses the 39-529 track slider or the 39-438B and 39-439B operators. The main difference between the two styles is the plastic guide at the end of the arm. Please review the video below for more details to help choose the correct style.

Also see the 39-451 and 39-452 or the 39-375 and 39-376 cover and handles depending on style preference. Let us know if you have any additional questions!
