raleigh58,
If you are interested in authenticity, do you have a 55-59 Factory Assembly Manual?
If it is like the earlier manual, it will show battery cable locations.
Most likely the battery cables were 4 gauge (2 gauge to 4 gauge should work fine). As posted above, be sure all battery cables/leads connectors are clean/shiny and use
anti-oxidant conductive grease on the connection surfaces (available in small tubes at most auto parts stores).
