I removed the stop from the right side (photo). I'm trying to replace the left side. Not sure if they are side specific.
I also need a new side load balance (34") and a retaining clip.

The part you're looking for is called a top sash guide. I actually do not recognize yours, but it looks similar to our 18-093. Could you possibly use this as a replacement? Look over the dimensions and pictures we show on the 18-093 store page and let me know what you think.
