Does anyone only where to get window glass channel isolator for the door?

not the vent window, but the part that goes up and down (sorry horrible description).

Funny story on this, I looked out the window of my apartment the other day and I had the windows down on the Jeep and watched a cat jump up on my hood go up to the window and do a action movie swing into my Jeep. alony the way he clawed the window channel.

yes I ran out there and scared the cat sheetless. after I watched this.
