Here are a few pics with everything installed.
The 6x15x5 bearings fit the carrier perfectly and require 3 of the the traxxas 6mm id teflon washers to space the tmaxx axle. I put 2 on the inside of the axle and 1 on the outside.
The hpi dogbone and long cvd cup work, would be nice to have a 73-74mm long shaft and use a med length cup but this is the best I can do with off the shelf parts.
Will get the other side done and post up some results.
