Hi there!
We carry a few weep hole covers like this but the best match will ultimately depend on the width and height of the opening. It's hard to make out dimensions from pictures but start by taking a look at our 26-173 and 26-348. Review their dimensions and compare them with yours to see if one of the matches up.
If neither do, I recommend our 26-186. This can work for you but as long as you're willing to drill installation holes on either side of the cutout for the installation pegs. Just be careful and make sure not to hit the glass in the window. Look this part over, along with the video below, to see what you think.
