Hi Lou,
For what its worth, I had the same kind of leak in the same area, and it turned out to be the lower radiator hose clamp. Needed some tightening.
If that doesn't do it, these radiators are easily repaired. If you don't feel comfortable with your own knowledge, call Tony Labella in Cherry Hill, or Bob Platz at Precision Auto Works in Camden. They might tell you the radiator shops they trust in the greater Philadelphia area.
