Nice bike. This machine is ~90% CT70 K0 and those parts are easily sourced in North America. The HL shell is similar to the late CT90/110; those bikes had the trapezoidal speedometer configuration. Your speedo is unobtainium rare. Some other non-CT70 parts can be sourced domestically, too. That heel/toe shifter was used on a number of other models, including the Cub. Dratv & NEVC usually have them in stock. The fenders, lower fork legs, footrest assembly, shocks & tail light assembly are more, or less, unique to the type I Dax and mostly have to be sourced from across the pond. Somewhat surprisingly, the fenders & fork legs can be had new, as NOS, or reproductions.
The list of hard-to-find parts is rounded-out by the tail light assembly, brake pedal, decals and...transmission shift drum. No North American spec CT70 ever had the 1D/2U shift pattern. And, there was never a CT50 version.
