FYI to everyone else, all this information was gathered by HAMMER DOWN, myself and groff, during our swaps.. this is real-world info, not speculation.

for the rear diff:

hammer down is running a re-geared WRX unit
i am running a 2004 legacy auto 3.90 (just broke it ), so i am swapping the 05 LGT LSD carrier into the 3.90 legacy housing
and groff is running an R180 and Spec.B Axels. (damn you! )
