I have extended my upper strap button as shown here: ...with a spacer nut. I'd like to replace it with a nice hardwood spacer. It should have a 4mm (5/32") hole drilled through the center; an OD of maybe 17mm give or take; and a length of about 38mm. The OD and length do not need to be exact at all. The wood could either resemble the clear amber finish on the bass body or the pao ferro of the fretboard, but it doesn't need to be an exact color match. Just something that will not look out of place. Let me know what you'd charge, and if you have any other questions. Thanks!
