I have a 1992 Fender Jazz Bass Plus that had the Lace Sensor pickups and Kubiki preamp. I have misplaced the screws that hold in the backplate that covers the electronics. There are metal taps in the bass body, so I believe they were small countersinked machine screws. I tried contacting Fender for the specs, but they were no help. Does anyone know the size of these screws or where I could get some replacements?
