I have brown aluminum windows in a house built in S. Florida in 1983.I have already ordered from your co. and replaced the channel balances. I am trying to find the locks for the window that are on the bottom sash and snap over the frame. It is two pieces around 1.25 long welded together at 90 degrees. On the back of the weld at the corners are two lips that slid into grove of windows. Any ideas?
