if you look at the LEX on these hornets, they go to the front of the front windshield. On the Super Hornet, the LEX only goes up to the front of the canopy. Also, the vertical plates are called LEX Fins which distort the air flow over the vertical stabs. The original problem was too much vibration on the Vert stabs. Another way to tell the difference between the Hornet and Super Hornet is to look at the horizontal stab, the Super Hornet has sharp angles. Also the Super has 3 weapons stations on each wing.
