You only need to swap core supports if you are going from one styling designation to the other, ie from 94-97 to 98+ or the other way around. If you stay within your years but simply swap to a different make they will bolt on directly. Some of the older swaps will require new light pigtails as well. If your lights are crooked they are not sitting in the core support correctly, they need to be adjusted, or you have some lousy knock-off lights.
