Did this mod several years ago:
The condition of your 46 year old original copper radiator probably isn't in as good condition as you might think even if its not leaking. Could be a good time to upgrade to an aluminum radiator and flush the cooling system. Aluminum transfers heat better and since weighs less aids performance. They are same unit as X/19 and available now. The aluminum gives the car a more modern appearance.
Ditch the heavier factory cooling fans for larger lightweight slim racing fans. Wire them both to run off the temperature sensor instead of having one wired into the AC wiring diagram. (Center tunnel removed for photo only). Some of you without AC probably have a fan attched not foing anything ever. Don't overtighten the radiator mounting nuts, the mounting bolts are weak so just enough to be tight.
Throw away crusty old radiator.
