Should you decide to try a repair, here is the method I was taught by one of the old guys. Drain the radiator, it's easiest to work on if taken out and placed on bench, table, or sawhorses, but it can be done in situ, as they say. Cut a bicycle inner tube so it's now open ends can be clamped over the inlet and outlet of the radiator. Replace cap and close drain. Clean and solder the damage, then use a tire pump to put a couple pounds of air in the tube and radiator. Spray the repair with soapy water. Bubbles or not will show whether repair is finished. If not pressure can be released quickly and soldering continued.
I've used this technique to repair a couple dozen radiators over the years. Some rather expensive ones in the mix, even with fan gone wild damage.
