Hello, Eugene! Based on your old stamp of "7#27," I recommend the Andersen 24-737 sash balance. |

The 24-737 installs using two screws that install on the flat tab you see on the side. I see a similar tab with screw holes in your photo so I assumed that yours installed the same way. Can you confirm? Refer to the video below to get a better idea of what I mean. |
