Gulf and Basco Replacement Shoe

Hello, I am trying to find a replacement for this type of shoe. The window was made in October 2007 by Gulf and Basco. The shoes have snapped off where they attach to the channel balance. I greatly appreciate your help.
Thank you
Kriss

I think I found the correct shoe. Could it be the 15.195 shoe? It looks exactly like it.
thank you .
