Why is seal kit 01-9042 specific to the 1977-1978 Honda CB750K and CB750F?

It contains the late 29.8 x 62 x 7 countershaft-sprocket seal used on the 1977-1978 models. Earlier CB750 applications use a 25 x 62 x 8 countershaft seal; kit 01-9018 includes both early and late versions when a broader year-range kit is needed.
