Hi all. Trying to reassemble an old bass (still not sure exactly what brand it is). Down to a couple of final things I need. One of which is bushings for the tuning keys. I am missing a couple. Seems all the ones I find online are too big. I attached a pic of one I still have. Basically the inner diameter is 12mm, outer is 15mm and flange is 18mm. I bought a set of fender ones without looking at the measurements right and they are noticeably bigger. If someone can point me in the right direction it would be much appreciated. Thanks.
