Hey, thanks for posting. The cover closely resembles our 39-152, which is most often u sed with our 39-264. I just cannot tell if you have the 39-264 or not. You might want to remove it from the window entirely just to confirm. If it is, and if your window was made from 1995 to 1998, you would also need our 39-362 adapter.
