Do you sell pile weatherstripping for this door?

I'm a new home owner. I have an aluminum sliding glass door that I'm looking to replace the pile weatherstrip as well as whatever insert is at the top and bottom of the doors. I can't tell what the material is/was at the top or bottom-- I don't think this has been changed in at least 25 years. I haven't seen anything like the pile that's on my door. Thank you very much for your help!
