I would find an old school radiator shop in your area...if that is all possible, most radiator shops now just replace them, they have no idea how to fix them...what is this World coming to?
Lucky for me there is an old radiator shop that's been in business for over 60 years that's only about 25 miles away...your experience may differ
Or...you could try repairing yourself, do you know anything about soldering? (you'll want an air compressor handy)
