These are the 3" high aluminum brackets that are mounted to the left and right sides of the 1969-1974 Airstream windows.
The four small holes are used to rivet the bracket to the window frame. The push arm operator for the window is mounted in the large hole in the bracket.
These are typically attached to the window frame using our VTS-3003 Tubular Rivets. Rivets and riveting tools are sold separately.
