Front strut mount parts

[Apharaoh06]

I am trying to find all the parts to install stock upper strut pieces for the front of my 2010 camaro. However, part #22816428, is discontinued. I have searched multiple GM parts sites, and am getting a conflict of the part for a 2010 Camaro SS.
Does anyone know for sure if this part was used on Camaros? Some sites list it, and others don't.

I have looked up that parts and have attached pics of suspension diagram, snd even looked at used strut assembly, but I cannot seem to identify the piece on used assembly.

That looks like the rubber ring that goes around the big washer where the strut comes up through the fender. If you lower the car, it won't even touch the shock tower. You can probably just reuse yours. I have four of them in a box of suspension parts on the shelf.

If you are lowering your car, it's possible that this ring may not even come into contact with the shock tower, so reusing your existing ring may be an option.
