Fix my orignal radiator or just replace??

I took my 69 340 rad to get redone. Old school guy that had worked with Glenn Ray at some point. Removed tanks and side brackets, and reused them on new rad. Added another(3rd row), widened tanks. You cant even tell 3rd row was added. Absolutely beautiful work.
Cost me $600 here in Ontario Canada.
Keep looking and get your original redone.
