Cables are the same except for the throttle.........civvy versions used the Amal carburetter whereas WD version used the Villiers 3/2 so post-war civvy cable will probably not fit the latter carb..........twist grip end was the same for both however........
As Dave mentions, the lighting coils and the ignition coil are the same.........
The timing cover (magneto cover) on post-war civvy however is cast with the wording "Royal Enfield" whereas the WD version is plain.............
