Just moved in and an working on repairing a few things. One of them is the balancers for a bedroom window. I have purchased new balancers from Great Northern Windows here in Bend, Oregon, and they recommended I contact you. They don't have any of the clips/inserts that go into the frame just above the lower sash. One of my attached pictures shows the parts in the frame on one side, the other photo shows the parts on the other side are missing. Can you help me find the necessary parts.
Thanks,
Steven
