Just make it clear to the buyer about what you did, so that somebody who knows what they're doing doesn't accidentally wreck the nut by using the tool they're supposed to use.That’s exactly the problem with my fury. I didn’t know it was metric and the ten prior owners probably didn’t know either. So I need the replace the bullet nut. I’ll put an SAE nut on there as a courtesy to the next owner, but if someone tries to return the bass because it’s not original as described, then my answer is no.
