This is the general idea. You need to get oil down to the sun gear
area. In this case a custom planet carrier would be drilled and a
tube welded in with a fitting for oil pressure from the engine.

In the case of the Ross a spacer plate may be necessary with the drilling
and tube added. Not all that hard to do.
