Well that's about it, just do a test fit to be sure you have made the mounting holes large enough, then pop it back on the car. On one of my cars with 4 mounts you can't tell it is there and can only barely make out the blue on the one with only two mounting holes but only if right up on it and if you know to look for it. You can see the reason I replaced the previous plastic which was thin and cracking. Hope this is useful to someone, next thing I am planning will likely be a custom grill and a custom CAI (Cold Air Intake) for the silver car, the black one is already somewhat modified.
