Hi there, I need to replace several window counterbalance parts and popout clips. The photos show one for a small window. If I can find replacements, I will order several more for different sizes. The popout clips are also broken or missing. These windows are at least 17 years old, when we bought this house from a previous owner. The only manufacturer label on the part (shown in picture) shows "10 4 L J CALDWELL".
Thank you so much in advance for your help. Kent
