Looks like there were definitely two different bridge pickups. The coil switching might be off the table then. - Roscoe Beck V: 0049725000 (4 conductor) - Precision Deluxe V: 0056135000 (3 conductor) <----- the one I have I did email my tech a few days ago and he responded last night. He was familiar with those pickup and said that it was probably the best one that Fender put out. He also said that finding a routing template online may be very difficult but that he could make one if needed for an upcharge. Either way he was optimistic about the pickups matching well and agreed that this mod would be well worth the effort.
