Replaced the tremolo on my Fusion III with this, had to take the bushings out too, since these ate different.
The VS100N is much higher quality, hardened steel, better string guidiance etc.
I had to remove a bit of wood for the trem arm and a bit more at the bottom of the pocket, since the 3 notches on the trem block are larger.
After that was done the trem was able to move back and forth without issues.
So now I have a Fusion III with a floating tremolo that stays in tune, the original couldn’t and even had issues when I did set it for dive only.
