Searching for pile weatherstrip backer

A quick learner says:
I have white pile weatherstrip (9/32" x 9/32") that came attached (glued) to a plastic backing piece that slides into my window screen top edge. I'm attaching a few photos of the plastic backing piece to see if you sell a replacement part. It has cracked and is no longer usable. I need a replacement for the plastic piece + the white pile strip. Do you have these?

Thank you.

Hello,

Generally, wool pile like our 58-022 with the same dimensions as yours installs directly into a track in the window sash. Unfortunately, we do not carry the extra piece that your pile was glued to. I'm sorry that we can't assist with that part of your repair.
