I had to order some more C6 parts from my supplier and asked him about the
six planet in the E4OD.  True, there is one and the entire set will
interchange as Brian said.  BUT,  this is the front planet set, not the
rear.  My drive uses the rear set which has the 4 planet set (and the
2.176 - 1 ratio).  Until we can make our own variable props, the 2.75 - 1
ratio is too much for 200 mph and up aircraft.  Would be fine for a slower
plane though.  The reason for this is a long story.  Many people have fallen
into the trap of going for the theoretical best configuration (i.e. longer &
slower props are better) only to find that real world considerations make it
the wrong choice.

I concur. Just curious about something Tracy. Is the front planet set
ring gear bulkhead shaft spline the same as the rear planet ring gear
bulkhead shaft spline?
