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." This is a set of bushings to fix the bridge (preventing it from moving back and forth) on Jazzmaster, Jaguar, Mustang, and other similar guitars. "1 set (2 bushings)" The dimensions are: 6.5mm diameter for the bridge post side, 8mm diameter for the anchor side, 13mm diameter for the flange, and 1.5mm thickness for the flange. Important 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 flange of the bushing 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 via Yu-Packet (delivery to your mailbox with tracking service) only. * To prevent any issues for both parties, we cannot accommodate requests for other shipping methods without tracking services.
