Two pictures above include 'unbroken' left side and 'broken' right side.
The window was getting difficult to open/close. I probably should have lubricated it. The bottom end broke off.
Hand written and legible on the right side picture is 7 and 7. The broken piece has a 6 on it.
The unbroken left side measures (roughly, I did not remove it) 1/2" x 1 1/4" x 5 3/4".
The windows are vinyl coated aluminum, I think.
And I assume I need 2.
Thanks. Chuck
