I agree with what others have said, coolant overflow tank, power steering and coil straps, were cad plated. Can't help you with the battery clamps. I know they are there but would have to climb under the car to see them and it is a bit chilly on that concrete floor for this old body this morning:-)
I am sure you have seen this picture of my engine taken a few months after delivery but thought I would post again anyway.
