Weather strip from tilt in vinyl window

Hello! Thanks for your patience during this busy season.

This foam seal looks like it could be a match for either our 58-171 or 58-182. The only difference between them is the size of the "T" strip.

I unfortunately cannot determine what that measurement is based on just a photo of a ruler. You will have to measure as carefully as you can and pick accordingly. If I were you, I would use a more accurate measuring implement. If you have calipers then now is the time to use them.
