David,
Apparently there is "no" source for the PCBs. With your connections, you
could probably prove me wrong on that.
You don't actually have to fully remove the screws. You can just loosen
them and then force a screwdriver between the PCB and the housing of the
AFM. This will offset the PCB just enough to put the wiper on a new track.
