The Gen 2 and the daytona/40th/special edition spoilers sit differently on the trunk. The Gen 2 sits further back and uses the factory bolt locations of a car with a stock spoiler. The daytona style does not sit as far back as the gen 2. You may have to fill in a couple holes and relocate the one's you need. Another option would be to buy the entire trunk with the spoiler or find a gen 2 style spoiler.
