There was a post from last year about a kit to swap in a Z32 or Armada diff into an S30. The company appears to still be in business, so I am gonna give them a call tomorrow and see what I can learn. The rear cover supposedly is interchangable, which should allow the same mounting position. The front mounts might be different, but I am sure there is something that can be done. I hear the yoke is huge fr the Armada, but a nice Spicer 1350 yoke would be nice anyhow :)
