Ray, this is going to require everything spotlessly cleaned & tinned and them pretty much soldered in place just like a radiator tank.
If you can handle this level of soldering using liquid acid flux and brushing the solder around you might find it a rewarding experiance...otherwise find a seasoned radiator man to do it.
I suppose you'll have to decide upon tank removal, or just washing it out on the car & maybe fill it with water and have a fan circulating the air over the top so she don't blow!

Oh ya...JB weld would probably work fine for a while at least...
