Why am I having such a hard time, finding 42mm wide flat bottom pre slotted Bass guitar bone nuts, its driving me nuts (pardon the pun) plenty of plastics out there, but I don't want plastics, Brass hahaha for god sake give me a break.
Does anyone know where I may be able to track these down in Australia, I can get 38mm, no problem there even 43mm. I have a PBASS and a JBASS both are 42mm wide at the nut slot. Been playing for awhile on my Basses, but never really had to deal with replacing the nuts before, I didn't realize there is such a variation.
So I have a question !!!
Are 43mm bass nuts a standard width for a 42mm wide neck and its just a mater of centering it then filling it down to suit the neck ????
Its probably a silly question, but I have found that there are 42mm wide flat bottom bone nuts, just not in Australia unless I want to pay a luthier $80 to have one made up from a blank. No thanks, i'll put up with the plastics before doing that, no offence to luthiers, but I just cant justify a $5 ready made nut to having one made.

ANYHOOT,
hope someone has an answer for me, thank your mother for the rabbits.
