the pics are a sample of the many conversions done using thick adaptor plates
where the starter area is grinded on the bell for fitment and the flywheel
should be ok providing there is enough starter teeth engagement.
Some extra width compensation can be gained from not using the factory spacer
plate and making sure the inside of the starter die has enough clearance all
around to allow the flywheel to sit nicely within the plate and allow the
starter to mesh well with it.
