EagleMaximizer window jambliner (Squaw/Olympic Valley)

I am looking for replacement jambliners for a 1999 Eagle Maximizer Plus double-hung window (which are not manufactured or sold anymore). One of the existing jambliners got warped due to a grill being placed too close to the window! Here's a photo of the damaged jambliner and two photos of the undamaged jambliner from the left side of the window. Looking for a needle in a haystack here and appreciate your consideration!
