MI window coil identification

Question

Hello! My window is broken and we only know that this is a MI Window but this piece I need help identifying to replace. I've attached photos of it broken and a photo of an identical window with a piece that is whole. There are no numbers to help identify the piece. Thanks for the help

Hey there,

Thanks for reaching out! Your window balance is likely made using the 15-180 Coil Balance Shoe, 15-181 Coil Support Detent Clip, and 15-182 Coil Bushings. To confirm that the shoe is the correct match, carefully look over the dimensions and compare them.

This assembly uses the Series 190 Coil Balance; attached using the 33-073 screw. To determine the correct coil weight option, you'll need to look for stamps/markings on the existing coils. If they are missing/hard to read, please see the tutorial below for instructions on selecting the correct coil weight option.
