The windows are heavy now both sides are broken .please give me the item #and I will order I need left and rights for 3 windows.thank you.

Thanks for your post! Your coil balance assembly is made using the 15-087 Coil Housing Pivot and 15-086 Tandem Coil Housing. You'll need to remove the assembly and compare the dimensions to confirm that these are the right replacements. If they are match, chances are the 15-086 should be as well.

These housings are both compatible with the Series 180 Coil Balance. Your housings are marked with the #4, so you'll need the S180-04 Coil Balance. These are anchored in the window track using the 16-024 Mounting Bracket.
