Hello, thank you for posting!

You will need to remove the coil assembly from the window to confirm dimensions, but please start by reviewing our 15-199 pivot shoe which is 17/32" thick. This shoe is compatible with either our 1/2" thick Series 160 coils or the 3/8" Series 165 coils. Please let me know if you have any questions.
