Take your time, it's not a race.

I had to modify my front parking brackets too, but mostly removing material on the bracket itself as it interfered with the air scoops I bought from **********. If you haven't bought them yet, do yourself a favor and buy the ********** offset grommets for the front bumper bolts. They are a life saver when trying to align everything and not chip the paint. The front end has about 2" of play in it (up/down) when aligning the brackets/front bumper and you can just hold it up by hand. It's easier with a helper though holding up the front nose and watching the hood alignment.
