Window springs
Thanks for your photos. Based on what I see here, you have either our S351-29 or S390-29, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
That would be the top sash guide. We may have a good match for yours, but your current guide is too obscured to ID. In order to make a recommendation, we would need you to remove it from the window and show me a clear picture of the front and side. Think of it like a mugshot.
I'm afraid this picture is not sufficient to make a recommendation. As mentioned in my last mentioned, we have to see it clearly from both the front and the side.
For now, you can consider our 18-009 as a possible replacement option, but there are many other possibilities. This one is just the frontrunner. Review its dimensions and see what you think. You can also see our full selection here.
