Default Calling all with JDM or GR drivetrain knowledge

I'm looking for any and all information regarding doing a JDM v7-v9 (v9 specifically) STI transmission swap into a HATCHBACK WRX. Finding info on swaps into a hatch is few and far between as it is, but I'm having a hard time figuring out what will/will not fit from the JDM swaps. I am assuming that the only problem parts I will have to work with is driveshaft, shift linkage, cradles, and suspension. Can anyone confirm this?*

A. Are JDM driveshafts any different from USDM?
* * 1. Are GR Hatch (08+) STI driveshafts different from GD (04-07) driveshafts?

B. Is GR Suspension different from GD suspension?

C. Is GR shift linkage different from GD?

D. Are GR transmission and rear diff cradles different from GD?

Any one who has any info on this would be greatly appreciated!!

C. yes, the GD linkage is something like one inch longer.
D. trans-I have a 04sti transmission & cradle in my 08wrx, no problems.

I put the r180 in, using my 08wrx rear diff cradle. the r180 hit the cradle slightly, I ground a bit off the r180(just the edges of a raised thick section) it fits. Looking at pics, the sti one has more clearance. The studs on the back of the diff are shorter on the 04 R180, I took the ones out of my wrx r160 and used them. (DSS axles, kept my 5X100 hubs)

(swap out your wrx 5mt, and the 6mt's neutral switch.)
