Missing part, I can not find

Hello,

The wings on your pivot bar are used to draw in the center of the window frame and prevent it from spreading. Since your windows have been installed for some time now, your windows should be settled. We do have winged pivot bars, but the hole dimensions and wing size don't match. We do have a few possible replacements. See our 26-366 die-cast pivot bar, as well as the 26-236 and 26-237 nylon housings for the 26-083 pivot bar. Look them over and see if one of these options could work for you. Thanks for posting!
