Old Barrier windows from upstate New York back in the 80s. Also need the spiral balance tool to get them back up in there . Also need the stoppers there about 5 inches long. Sent pictures see if you can come up with anything.

Hello! Please see our 26-028 Tamp-R-Lok. This looks to match the little piece you show in your pictures. As for the tool, see the 75-006 charging tool for tilt window spiral balances. I'm afraid we do not carry sash stops, unfortunately.
