Bottom vinyl seal

We may be able to help, but I cannot identify a match based on this picture. We will need you to remove a small sample and show us a clear picture of its end profile. We will also need to know the end profile's dimensions.

It's hard to tell. It looks like an important portion of the seal ripped off the sample in your picture. I can't see how it installs in the window. You might have something like our 58-171 or 58-182, but you would need to compare the size of your T slot and size of the bulb to ours.
