Well... i'm either lazy, or a genius. The grille is complete is a hacked way, but it actually ain't too bad. All my schemes for attaching it have been thrown out the window. But before we skip to the end, let's continue the story where I left off....
The block behind the saturn logo needs to be cut out as follows (also notice my cut airbox behind

)

You can see that it's not too open behind the plastic so you aren't magically getting tons of air into the engine bay by cutting this part or any of this area out.
So my 3rd plan was to use the stock backing and attach the metal sheet to that, then attach the grille to that. What I didn't realize is now you will run into a clearance issue with the hood! The top of the mesh would rub against the hood if you open and close it. If you pull it down so it doesn't hit, then there is a gap and it looks stupid.
So I knew I had to ditch the stock piece. So I was going to just put the aluminum flat where the stock piece is and screw away. But then how will I attach the grille to the aluminum... Maybe an adhesive? who knows. So I said F it because I've spent 3 nights and now my entire saturday on this and thought, maybe I can just TIE IT.
So i cut the mesh to fit into the space where the stock piece fits. And grab some wire and tie it over the top like this.

Why didn't I just think of this from the start!


When you close the hood you can't see it. And it seems to be on there pretty solid. It doesn't move around at all...

The mesh isn't cut too straight. It's very hard to get a perfect edge with the snips. The only way to get it perfect is to have a better cutting device or use a grinder. I just ran out of time.

So I think it looks pretty good but the silver color is too "blingy" for me. It really makes the car look meaner. Painting it dark grey should help even more. I was thinking of going black, but I really want some accents to break up all the black.
I have to decide if I want to paint the grilles below the same color as the mesh. I suspect I will. I wonder if they can be easily removed to paint...
What needs to be perfected
- I need to work on my hand strength, it's killing me from those snips!
- There has to be a way to make a better pattern, because cutting to fit and getting a good edge is impossible.
- I should have looked into what the aftermarket kits use to attach. Could have learned something. Does anyone have an aftermarket grill and have photos of the back?
