Hello, thank you for posting,

It appears your window uses an older coil balance system that is no longer made. We recommend converting to the 15-259 pivot shoe and Series 159 coil springs. Please review the step by step video below detailing the conversion and additional parts needed. Let us know if you have any additional quesitons!
