Thanks for contacting us, John. I made up a list of related parts for your window on the upper right hand side of this page. Majority of the time, the pivot shoe or Series 190 coil spring breaks. If it is the coil spring you need to have replaced, we will need the number stamped on the end of the spring that is screwed to the pivot shoe.

Looks like you also need the 15-180 Pivot Shoe, which uses the Series 190 Coil Balances. Let me know if you have any further questions. |
