lucas part no MN1 XX 46021d
They changed after mk 4 to a slightly different beast
the front flange makes them different from most other magdynos but id talk to a magneto specialist, as some models can be made to fit
i havent seen any on ebay in 6 months of looking, but they shouldnt be too rare they only fit douglas because of the flat twin the spark is 180 degrees apart
ill be looking next week for one if i find any ill let u know
