Before you buy anything I think we need to determine exactly what engine covers are currently on your car.
by your VIN number your car should not have an outside fuel door. But in the post by the previous owner which you recently commented on, the photos show an outside fuel door.
I strongly suspect this is where your fitment problems are coming from.
I think a previous owner converted your car to an outside fuel door, and the left-hand engine cover is not original to your car, or to the flat center screen
if I were you, at this point I would remove all three engine cover pieces, take good photos of each piece, especially on the edges that meet the center cover, and the edges at the rear window, and post those photos for our evaluation.
or you can buy a replacement center screen and then find out your problems are all connected to the left hand engine cover
