Channel balancers for a window from approximately 1996

Question

I need left and right channel balancers for window that installed in a new house in 1996 or 1997. The photo with the "unique" label is for a similar balancer that was installed some years ago in a similar window. The other 4 photos are of the broken balancer (you will notice the spring is missing).

User submitted photos of a window balance.

Hey, thanks for posting. I've narrowed this down to two possible channel balance Series: either our Series 380 or our Series 385 balances.

Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 380 uses the 15-005 while the Series 385 uses the 15-004. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match.
