The support is 1 & 7/8" till
1 & 1/4 "wide at widest part amd the main part of the support is a little less and the support also has a rib facing the inside of the window

Thanks for reaching out to us! We have a handful of coil housing similar to this so we'll need more information to help narrow down some options. Can you show us a photo of the pivot shoe, preferably removed from the window track? Identifying the pivot shoe will allow us to determine the compatible coil housing.

Thank you kindly! Our 15-111 appears to be a match. This is compatible with the Series 160 springs that use the 15-150S support for a single coil spring. Take a look and see what you think.
