the vfr frame is alot bigger than a mc21 i suggest that u park your 21 up next to a vfr to see the differences for your self as no1 here has replied has made me think that no1 knows,
i owned a nc30 many years ago and from what i can remember they may loock the same but are so much bigger the angles would be wrong.
u could buy some carbon sheeting and make your own just mock it up with card board first,
i personally am going to get my 21 frame painted when i get round to it a nice satin black
