Thanks for contacting us. Looking at your photos for each of your three windows, I believe you have either our 39-253LB and 39-253RB or the 39-438B and 39-439B, depending on the slider at the end of the arm. The video below will explain the difference in more detail so that you may pick. Regardless of which one you go with, you'll also want the 39-452 and 39-451, which are sold separately. |
