Howdy,
In my humble opinion you are probably looking at a repaint in order to do it correctly. You will need new quarters and at least the outer wheel well half. For the front, assuming the headlight backing plate isn't in the way, you can easily bump it out from the inside. If indeed it is in the way, stud gun and puller would be your best bet. If you can find a painter to color match and touch up, great! Otherwise, the car should probably be completely resprayed.
Not the cheapest or easiest solution but the car show/concourse correct in my opinion.
