ok.. here is the best i can come up with right now. using rear diff outddrives from MR4TC, plus the rear cvd's from same car, you can almost get there. as you can see in the pix, the Yoke takes the 6mm i.d. bearing- the Tamiya is 5mm. couldnt find a 6X11, so the best way i could come up with was to use a lathe to turn down the Yoke cvd... (actually, i used a dremel on a junk one to mock it up- lol...) seems like the length is fine, and there is minor shimming on either side of the diff to take up some slack. that F201 idea might work too, but i didnt have any of those to try! pix to follow...
