Hello, thank you for posting,

Please review the style of the 15-087 pivot housing that is compatible with the Series 180 coil springs. Review dimensions below to confirm a good fit! Also see the 16-031 mounting bracket. Let us know if you have any additional questions! 

I cannot confirm if the original housing has a 6 or 9 stamped on it. You will need to weigh the sash to confirm. If it is a (6), the sash should weigh 12 pounds or 18 pounds for a (9) stamp.
