Because of the production required to get to the car take a new/good battery fully charged for sure. Mount it temporary if you have to. I would check the battery end connections, not just ON the battery post but where the cable goes into the battery cable end connector.

Solenoid is also suspect, there cheap and fairly quick to replace/rewire temporarily. Just get the "standard" Ford solenoid like just about every Ford made in the 60's, 70's and 80's used!

The "clicking" sound indicates a bad connection somewhere (at the bat posts most likely) or a bad solenoid. Could well be the battery is "done" and WON'T take/hold a charge.

Very unlikely the starter AT THIS POINT because the solenoid has not yet engaged to provide POWER to the starter.
