Does this part look familiar? The one with the yellow circle.

Pretty sure it is compressor brace, but cannot determine how it fits.
The compressor mount part I understand is the following two pics: red bolts to the red holes.
Still there are a two bolts, the green ones seem to attach nowhere. But they are in my bag of AC parts from three years back, so they are part of the puzzle.
Trying to determine what I would need to mount a newer style compressor.
