I have a MY05 RS, most was the same I just have a couple of observations. I also have an Australian vehicle, so it might help any fellow Aussies. This has been posted on a couple of other forums.

ScoobyMods has a very good write up at:

Instead of quoting the whole thing, Ill just add some points. I did all bar the replacment of the actual rails (more on that later). I own a MY05 RS, so this should clear up any issues. The numbers relate to the paragraph numbers from the above link.

2. When removing the handles I pulled the actual handle towards me; you can see two bits of metal come out about 5mm from under the covers. I just pried the covers up and then slid them into the centre; this exposes the screws.

3. I just popped the top half off, that exposed the bolts. I found the passenger side bolt to be very very tight; much more than anything else.

4. A-pillers were easy; if you pull them right out (I did) then they are easy to get in; you'll see two slots that you put in first. B-pillers were harder, the bottom half has a plastic rivit on the rear side of the B-piller; bloody tough to pull out. I ended up just using the plastic piller surround as leverage.

5. and 6. Swap these two steps; only minor but will allow more options in removing the C-D pillar.

8. and 10. Use a flat bladed screw-driver to loosen the lens, like the link says, don't twist. Just lever back and forth and the lens will slowly slide out. Leave the main light attached, you can feed it through the headliner.

12. All the racks nuts were in obvious places; there are 8 in total, the two rear ones are hidden behind some metal structure (but are easy to access)

13. The holes can just be filled with nut and bolt and waterproof washer. I have left this step undone at this stage as I do not have the trim.

15. Remember to keep the rubber stripping around the doors over the trim panels and roof liner.

Other points:
- When the racks are removed (pull upwards) slide the larger of the trim pieces rearwards (this will enable you to use the clips).

- The front trim pieces have clips and a plastic rivit thingy, pull upwards.

- In Towoomba at least the Subaru database was mixed up; the hatch pieces were listed as sedan and vice-versa. Ensure that you get 91046FE000 and FE010, not FE061 and FE071. If you are careful when removing the trim you will not need to order any more clips from Subaru.

- Our rails come from Japan; expect 2-3 weeks. Cost was ~$125.

Any Q's just ask.

Cheers,
