Just use the Legacy diff housing so you don't have to mess with the pinion preloads and stuff. Then hope that the SVX diff (You do know to put the 4.44 ring gear on the SVX diff right?) fit's into the Legacy diff housing, some of the non LSD cases need to be grinded out a little to fit the LSD diffs. Usually if you use the same shims that are on each side it will work OK. If you have the measuring equiptment then you can check the back lash and preload with it but I usually do it by feel (No problems yet) and check the gear pattern, if the gear pattern look good and the diff isn't too hard to spin then you should be good to go. You also might have to change the driveshaft flang, I know the SVX one is bigger than the older Legacys but I don't know if they made them bigger in the newer ones, just touqe that to spec and start doing AWD burn outs.
