I called and they asked me to send pictures. Weatherstripping for a storm door circa 1990. Glass says guardian Need the side for latch. Probably about 7 feet. I saw a picture of the swisco 58--008. If I cut off the kerf and trim the t part down to 3/16 it slides in snugly.

I agree, our 58-008 looks like the best match in our inventory. I can tell you that we don't have anything closer. If that won't work for you, then I don't believe that we have anything that will.
