Alside Window Coil spring replacement

Question

Hi -
I had trouble opening/removing a window and discovered the shoe on both the left and right coil spring was damaged. I looked at your website and think the series 140 Quick tilt is the part I need. Just looking to confirm. I only removed the left coil assembly Not pictured the coil is stamped with a "9" so I think I need a left and right 9lb rated 140 series quick tilt.
Also - as the actual coils appear intact - I'd like to keep a back up set and repair the existing coils using Product Code: 15-215 Quick-Tilt Pivot Sash Carrier.
Am I on the correct track?
Thanks in advance

The Series 140 may work for you, but the pivot shoe uses a different style cam compared to your original. That means you'd have to replace the pivot bars, too, which can be an uncertain thing depending on the size of the existing ones.

A better option would be our 15-177 pivot shoe, along with the Series 152 spring. These are explicitly designed to replace your original and be used with all the same hardware. Your old cover looks like it's in good condition so it can be reused.
