Do you have any updates?  
  
I'm curious to what you have done for retain abs.  
  
Your post is the latest one I have found so far..  
  
I have a 300zc twinturbo with gtx2867 twinturbos. I picked up a 370z 6speed transmission that I would like to use and the armada rear diff ~2.9 ratio seems it would be my best bet. (or an older m45 r200 3.13ratio and swap in a 350z lsd so I still have the 31spline/32mm output stubs and I will be able to use z32tt shafts so it is fairly robust throughout.  
  
Although the armada r230 is just so much larger of a unit internally.. I would feel more comfortable using that so it could handle my drag launches etc better I would think.  
  
Do you have any info on the shop that is doing your diff conversion? I may be able to do most here.. As I read of a Timken bearing that alleviated the issues of alignments/shims that one of the other members had using the z32tt lsd in armada housing.  
  
I really would like to keep ABS.. And reading about how the armada diff doesn't have provisions.. I am unsure how that would be a possibility.. Unless it's something simple as welding/machining clearance on armada r230 on a fitting to attach the sensor to the diff housing using the z32tt cover.  
  
What did you do for parts like crush sleeve etc?  
  
Any info is greatly appreciated!
