Test fitting the neck pickup. These pickups have “vintage” style cloth wires. Be sure not to strip them involuntarily while pulling them through the body! White “dust” is wax that comes off the wires as you string them through as these were “potted”; inundated in molten wax. It also came with a rubber band probably protecting it in transit.
Rubber surgical tubing is used as bushings between the baseplate of the pickup and the screw head. Unfortunately, this body was routed quite deep, something Fender didn’t anticipate with the mounting hardware supplied. So I cut two pieces off a wall plug as bushings to get the correct height, under the baseplate.
