i dont know if you have the front fenders bolted on yet but its best done with them off. you can slip a small tape measure at the body line and measure how much you need to come out. the fenders being off you can bring the door out to match. if they are on just do so then open the door, loosen up the bolts for the hinge, close the door and gently pry the fender out to match. make sure you are gentle as to not bend the fender!
