I know I need a T slot foam filled bulb weather seal, but I am not sure which size. I have photographed a section of an old seal with a ruler in hopes you can help me identify the correct size I need.

I believe you could have the 58-182, which has a 3/16" T-kerf. Check to see if your kerf is also 3/16". If not, we also have 58-171, whose T is a little larger.
