Hi been reading some old books, Franks and Garratt, much more information ln them, So the Norton twins run from 1948, the clutch being altered slightly, can an earlier pre-war clutch be used in a 99, or a Pre-1956 unit, or is this a no-no! I know that the clutch design changed slightly and then later changes in 1957, so what is compatibility like speaking of engine n' clutch function?
Cheers
