If you want it to line up perfectly with the GT hood you have to put new holes where the top clips go it to pull it back more from what I've read and seen.
There is no gap actually the cobra hood is shorter than the GT hood so like silver04gt said you need to move those clips back or your hood will smash down on the grill post a little when closing your hood.
I work at a shop so I am gonna have our body shop do it cause the hood got hit too. They can do all that without a hitch then. Thanks for the help guys.
