I have an early 2000s JS100. It came with the nut clamping blocks removed and missing. Do I need to replace the whole nut or are the blocks the same for all Floyd Rose style nuts? I have a Gotoh GE1996 trem on order and will be replacing the lo trs 2 crap job that’s currently on it. If I need to replace the whole nut, what size do I need to look for?
