Chris, I had my radiator redone at a place called Atlas Radiator on I think Studebaker & Leffingwell in Santa Fe Springs? but they should be in your local phonebook. I had the top header eatan by a fan blade and they fixed it (no leaks) also had the thing boiled out as it was only a year old. They also fixed a leaky heater core that I had taken out of my car after it burned my little toes. All total it cost $150.00 and they gave me a 1 year warranty on the labor.
