Why don't you just pay someone to do it? You could simply bring in the side scoops and they would not charge really too much labor and if you brought in the car they can match it to the color. The thing with paint is your paint code won't match your car because the paint on your car will be faded from being out in the sun for 8 plus years depending on what year your car is. Trust me, I bought a set of mineral grey side scoops from a mustang gt same yr as mine and put them on and even if you look real close you can see there is a different shade in the paint on them vs the car and they were the factory paint job.
