Find a rust free southern car that has been hit hard in the nose.. Have someone cut out the sections that you need and weld them in. Always cut out more that just looks rusty. You cannot weld to rust. Final step, move to the place where your rust free parts came from.
FWIW, rust repair is arduous work that few enjoy.
