GOTOH SD90-SL RELIC Conversion Bushings. I purchased tuners, but the bushings didn't fit my guitar, so I repurchased bushings and have these unused ones left over. • Inner Diameter: 6.0mm • Outer Diameter: 8.8mm • Quantity: Set of 6 • Specification: Relic finish (New, Unused) I've included photos measured with calipers, so please check the size in the images. These are suitable for converting GOTOH SD90 series (Kluson type) from a 6mm hole to an 8.8mm hole. Although unused, these have been handled by a person, so please understand that before purchasing. Immediate purchase is OK. ※ This is an auction for the bushings only. Cases and packaging are not included.
