I have a friend who takes the centre out of the original wheel and rewelds it to a modern outer ring, i have seen many of the ones hes done including a morris oxford (moggy minor on steroids shape) running on 205/65/15 tyres, looks sweet as does the very early split screen morris i gave him which is running on wide metro rings. i think this route is much safer than banding. you can also choose the offset as to how far out you want the wheels sticking out!! he has all the run out dials and balancing machines to ensure all is true. can pass details either way.
