Squareback vs round back alternator?
Something like this.
The relay may be totally unneccesary with a new key switch.
It might still be useful for headlights and fog lights.
Headlight wiring and switches on the 1960 model are likely different than later A-bodies and B-bodies.
On the later A-bodies, there was a single pair of 40 Watt headlamps. The wiring path was long, and used relatively small wires. So the circuit does not fair well when higher wattage replacement lamps are used. In US this was 6012 bulbs being replaced by 6014, and of course in more recent years H4 type lamps.
We see in the 1960 main circuit wiring, that power from the alternator connects first to the headlight switch. So that is one difference. I'm sure we will find others.

Using the maxi fuse in the battery line A1 is a great idea.
Going by the standards I find on the internet, 87 is power out when the relay is turned on.
