Radiator advice…

I got my '74 Valiant Scamp slant six automatic fired up earlier this week and took it for a short drive around the neighborhood today after installing a new gas tank. When I parked it and shut it off, I could hear a hissing sound, and I could see some moisture on the radiator.

Is having a radiator like this repaired even a thing anymore? Is there a go-to aftermarket radiator I should be looking at instead.
