Help identify replacement balancers

A home owner from Olathe, KS says:
I need to replace some broken balancers on an older Weather Shield window. The home was built in 2005. These are vinyl windows. The existing balancers are 31 inches long and are marked with 30TG. They don't seem to have a foot on them. It just has a rope that extends down to a slider in the window frame.

Your balance definitely has a shoe. I can see it in your first photo; it's that blue piece, which is called a knife-lock shoe.

We should be able to help with this but there's a good chance that you have a non-standard configuration, if that shoe is any indication. In order to verify I need to see it removed from the window and without obstruction. Please let me know if that's possible.

I'm not able to remove the shoe piece from the window frame (without breaking it). I've attached a photo of the piece. I've also included a photo of the piece on the window pane that the shoe engages with. I'm afraid I'm going to just need to get a balancer that I can run the rope to the shoe and tie it in. The current one just runs through the piece and has a knot in the rope to keep it in place.
