I’ve looked all over the internet for this part, but can’t find it. Can someone help out with a link? What’s it even called? It’s where the radiator supports mount.

I took a stab at finding it on the infiniti parts catalog, but not sure if I have the right one or not.

I'm thinking they call that the radiator support panel reinforcement, but I could be wrong. Their pictures aren't too great.

What's wrong with the one you have? I'm wondering if you can fabricate another one, or worst case, get one from a junk yard.
