The end of the plastic piece seen in IMG_0126.jpg cracked when I opened this window. I have also included pictures of the label on the window.

Hello! It's tough to say for sure what you need while it's still installed, but I think our 26-243 is a great place to start. Look over our photos and dimensions and let me know what you think. For the opposite side, see our 26-244.
