At SUMI Guitar Parts, we leverage our experience working in musical instrument stores and guitar construction & repair to offer high-quality products that "clear a certain level of quality." These are bushings to secure the bridge (preventing front-to-back movement) on guitars like the Jazzmaster, Jaguar, and Mustang. "1 set (2 bushings)" The dimensions are: bridge post side diameter 6.5mm, anchor side diameter 8mm, flange diameter 13mm, and flange thickness 1.5mm. Notes: Some guitars will 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 be responsible for 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 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. #Jaguar #mustang #jazzmaster
