well i've so far managed to get hold of an nc24 swing arm and an nc30 rear wheel for the grand total of nowt. just need to mount the rear wheel which will require the four bolts removing and replacing with mounting pins, so i may have to get hold of an nc30 hub instead
.
the nc24 swing arm has the shock centally mounted ( not off set like the nc3) so think it will mount in my mc18 frame without to much fiddling!

does any one know how wide the mc18 swing arm is at the pivot where it mounts to the frame, or has one loose they could measure?
