At SUMI Guitar Parts, we leverage our experience working in musical instrument stores and building & repairing guitars to offer high-quality products that "clear a certain level of quality." This is a set of bushings to secure the bridge (preventing front-to-back movement) for Jazzmaster, Jaguar, Mustang, and similar guitars. "1 set (2 bushings)" The dimensions are: bridge post side diameter 6.5mm, anchor side diameter 8mm, flange diameter 13mm, flange thickness 1.5mm. Notes: Some guitars may fit these bushings perfectly, while others may not fit quite right (too tight or too loose). If they don't fit, please try the following: If too tight: ・Apply lubricant to the bushings and bridge posts, etc. If too loose: ・Wrap masking tape around the bridge posts, etc. *We cannot address installation issues due to the guitar's inherent precision (individual variations). For example, if there is a significant misalignment between the bridge holes on the pickguard and the bridge holes on the guitar body, the bushing flange may interfere with the pickguard and prevent proper installation (it may be possible to install them by shaving the flange). *Please be sure to check the dimensions of your guitar's bridge carefully before purchasing. Shipping is free and will be via Yu-Packet (postal delivery with tracking service) only. *To prevent any issues for both parties, we cannot accommodate requests for other shipping methods without tracking service.
