I ask for your help,

the NC30 frame and swing arm 89, 90, 91, 92, 93 and 94 ~ are all equal or is there some specific changes?

I await your response as soon as possible and thank you for your support.

They are all the same across all years of the VFR/NC30

They're all the same AFAIK.

Ohh thank you very muchhh!!!! :)
