Sash spring

Hmm..It's a little difficult to see what parts you are showing us with it still being installed in the window. At first glance, it looks like you can go with our 15-186 coil clip, and 15-180 coil balance shoe. You ultimately need to remove both parts from the window and match them up with our parts to confirm they are compatible with one another. Both of these pieces can be used with the Series 190 coil spring.
