Great looking wagon. Fortunately, that rust seems to be in the front end, which is interchangeable with other years and other body styles. The hardest parts to find will be the wagon-specific parts. Either way, these are great cars to drive. I have a feeling you will find the rust in the front fenders is coming from the inside out. What was not on these cars were inner fenders, so the muck off the wheels scoured the insides of the fenders, removing the paint and other rust inhibiting coatings. They can be repaired, or with some luck, replaced fairly easily. Good luck, and have fun around here.
