You're going to need new fenders. Some quality fiberglas filler work would get those going for the short term, but long-term, they're dead. I'm going to guess that the lower edges are toast, too. If, somehow, the normal lower edge rust spots are all OK, you might be able to find some fenders that are rotted at the bottom but solid where you have holes. Unless you're doing the welding yourself, it would likely be much cheaper to find new fenders, though.
