Welcome to the Forum, you will love the car. There are at least two Li. Brackets.I finally got the better one. The bumper has a high spot in the center to center up the bracket. I used a good level, but also found the bumper to have a v shape that fits the bracket. If you just take the bracket and slide it up and down and across it will be clear where it should be mounted.
A level never hurts though and just get it centered.
