A couple more points I just remembered...
Yes, I have Traxxas CVD's on the rear and stock plastic sliders on the front. I split one of the front drive cups and don't feel like dropping $55 on a whole set of CVDs to get that one part right now.
The rear-center driveshaft is made from multiple stock shafts that were combined and glued. One of the joints was left free to plunge like the stock one. I saw this trick here at RCM on an EMaxx I believe
