Thanks for posting the additional images of #2 Grille, in theory (to my understanding) this version never happened (outboard grilles with inboard mesh pattern material).
JD: I bought an early GT 350 project about a month ago....
And I'm trying to sort out these grilles.
I received (5) ...Inboards/Outboards/Reproduction/Original...
Can you see how I could get confused?
LOL..!

Yes, thanks for posting the images.
On this topic see attached, repro inboard grille -
note this is the later vertical upper grille version that fits and fills the upper opening. These have added segments (added on each side/end) to make the grille wide enough to fill the upper opening.
The grille mesh is available in 3 foot and 4 foot widths, the maker is buying the 3 foot version which is not wide enough and then adding extra material pieces to make the width fit the opening. Note weld on back. The 3 foot material the last segments go with "wide, narrow, wide"
An original, see attached front and back, note the vertical ribs hold the "wide, narrow, narrow" pattern (every 3rd vertical rib is wide followed by 2 narrow) all the way across.
All versions have a wide center vertical rib.
