8 Brackets and 8 Lever Assemblies

A handy person from Naples, FL says:
A plastic bracket that holds and houses the bar of the lever mechanism. Circa 1983.
Location of bracket is within the window frame, at the bottom, on both sides of the upright section of the frame.
Purpose: Holds a bar in place while lever mechanism leverages itself in and out against the stabilized bar.
Also, need the bar and lever [they go together as one part -one lever each side of the bar] The bar is attached between each lever at each side, the end of the bar protruding through the lever into the bracket. In the pic, 1125 you can see one rusted end of the bar through the lever and into the bracket that is still attached to the window. The bar is slightly less long than the width of the window, 40.5 inches. Manufaturer is P.G.T. Inc, see pic 1129. Pic 0228 shows all four windows, closed position.Pic 1127 shows the brackets removed. Pic 1124 is another angle of the lever and bar in position and into the bracket.

The Torque Bar Bearing or bracket looks possibly like our 36-019; take a look and see if you agree. I am afraid the bar and leaver itself we cannot replace, just the awning window operator itself. A local hardware store may be able to help you. Apologies for any inconvenience.
