Post a photo of the back of the trunk lid
I don't recall there being odd shaped clips BUT the 4 outer holes might take an offset clip.
The 4 acorn nuts go on the studs that are in the outer 4 corners.
All of the clips go in through the cutout

You have 12 main clips and 4 end clips.
The count is good.
I'm up to 98.5% certainty on what I have noted.
I really can't place the 4 on the far right of your photo.
The dress up full panel screws on to the trunk with small screws, before the 4 trim pieces.
The many small holes in the center of the trunk lid get water resistant tape over them, they are there for lettering if not a GT.
Wish I had taken photos!!!! Aaarrrrgghg!
