Thank you for your patience during this incredibly busy season. I apologize for the long wait.
Your operator appears to be an older version of the 39-171. While the shape of the base is a little different, it should still work in all the same applications as long as the dimensions are the same. You can even reuse your sash bracket.
See our 39-172 for the opposite side.
