Balance Keeper

Needing help with this part. It is a spiral balance keeper or shoe for a 60-70's era aluminum single pane window with a 3/8" spiral balance. The bottom sash has spring loaded pulls on bottom that release from this part and allow the sash to be raised and slide to the side and removed, I assume for cleaning (old school tilt window). I have noticed Product Code: 15-040 looks similar and may could be modified to work but thought you may have another suggestion. Thanks.
