I think it may be easier to find a starter gear with the correct tooth pattern instead of afro-engineering a bunch of stuff on the flywheel. Thats the only reason for needing the different flywheel anyway. Don't you think???
Actually, both the 130T and 143T flywheels have the same tooth pitch, the only difference is the number of teeth and the diameter of the ring gear. Both use the same starter, so no the ring gear isn't the reason for the different flywheel.
The reason is the need of a tone ring for the computer.
