i just did this. I used 98 outback struts, springs and top hats. the fronts bolted rite in. same top hat as the legacy. I used some camber bolts on the bottom whole of the struts (front) to get good camber. The rears don't bolt rite up. I took a 3/8 drill bit and drilled a whole on the out side of the original top hat hole. The out back top hats have a wider hole pattern. Its just tin and really easy to drill. I then used 3/8 fender washers to back up the nut. I used camber bolts on the rear too. I didn't change the rear arm and I don't think I need to the wheel looks quite centered.
This took about 4 hours. I did it rite in the drive way. Hardest part was un bolting the struts. I like the lift a lot. I really is a big change of stance and driving. I put bigger tires on too . My old struts had 250,000 on them and totaly blown up.
the first out back, 95/96, struts aren't any different than the legacy no lift.
