72 Dart acts like low battery but will start at relay
Next time try removing the yellow (in 1967) wire and providing 12v to it on the relay. That will test the relay by eliminating the ignition switch. If it starts then there is an issue between the relay and the ignition switch and back to the battery. Or the NSS side of the circuit.
B is from battery and from Alternator (via ammeter (1967)
S is to starter
G is to NSS (ground)
I is from ignition (yellow wire in 1967)
Get a remote starter switch
And put it between the I terminal and the battery plus.
You might also want to get a jumper to jumper from the G terminal to battery negative (be sure car is in PARK or NEUTRAL, with the parking brake on)
This little test will pinpoint your issue,
If remote starter starts fine after a clicking attempt. The relay is fine and the NNS is fine. It is the ignition switch or wiring
If the remote start gives you a clicking event then jumper the G terminal to ground. If it starts, the NSS or wiring is at fault.
If the above still produce a clicking event then the relay is at fault.
This is all based on the simplicity of a 1967. The later years introduced seat belt interlocks and other lovely "safety" features.
BUT the above should point you in the correct direction to start tracing out wires
