Building a G3R need some help!

[Traxxas Addict]

I'm thinking I'll mod the Revo input shaft as I have no idea when the slipper kit will be available. Probably around the same time as the new V3 Diffs!

I have gone to the Traxxas site and have looked at the exploded diagrams for the old E-Max transmission but I am having a hell of a time determining which parts I need as I am thinking that with only half the case there must be some of these parts that I don't require? Or am i just ?
