Source for replacement radiator

Hello!
I'm restoring my 1960 Pontiac Catalina. Unfortunately, before I got it, someone had taken the upper radiator hose off and it's full of mouse nests.
I'm searching for a source for a new radiator that will fit without much/any modifications. Does anyone have a source that might have something? Most of the "performance" outfits don't have any similar to the stock radiator.
Thanks in advance!
Tony

If you are fortunate enough to have a radiator repair shop nearby they can strip, clean, and recore (if necessary) your radiator. These older radiators are made of brass and lend themselves well to repairs while the newer aluminum radiators are basically throw-away units.
