Truth Hardware Pivot Slide Assembly

I recently received parts for this very window and they worked perfectly!I now need more parts,see attached picture, thanks. I would need to replace the rusty arms.

Hello-I am not sure what this piece is called but it goes along the BOTTOM on my window. The Operator is a single arm operator that clips into this piece and pushes the bottom of the window out, tilting the window towards the sky.

Need 2 mechanism for both sides and lower clip for bottom mechanism
