I don't see mutch differance between them other than the control arms and shocks and springs, but I could be wrong. The 04's suspention is so mutch better than all of the other subarus, in my mind. It is extreamly well ballanced. And it has 8.4" of clearance. I don't think that there is too mutch differance, but it would be getting a hold of them for a price that would make it worth while.
