Breaker points
With the breaker bar screws removed, fold it back out of the way. One of the coil wires is soldered to the breaker bar, as long as the solder joint is good, no need to unsolder it.
Underneath it is the contact points assembly. A number of insulating plates & spacers are in there, along with the spring steel contact arm.
Remove the 2 screws & note the parts arrangements.
