Yep there the ones I was talking about Jono. Look how straight the ring gear is!!!
Just to clarify the differences in flywheels between models.....
All K flywheels have the same bolt pattern on the back of the crank from K - 7K.
K - 4K all use a 180mm clutch plate (even if the GB input spline is smaller) so are all interchangable.
I am not sure on weight differences between them however.
5K from KM20 liteace van uses a 200mm clutch plate, so the flywheel has a bigger contact area. These Flywheels can be used to fit a K-T50 (with T18 clutch kit), or a K-W50 (with km20 clutch kit), but there is no clutch available to use them with a K40 or K50.
KR42R Townace 7K's have a 215mm clutch plate/flywheel. These fly wheels can only be used with a K-W50 or the K-W56 from the townace, both using the KR42R clutch kit.
