I ordered the spoiler direct from my Subaru dealer just so I could get a good deal on a professional install but you can get them for a few bucks cheaper from most any supplier out there. I've found that www.subarupartsforyou.com has the most extensive parts listing and some pretty good prices. That's where I ordered my grille.
i had to claim the plate before the turbo engine swap. i'm waiting a few more months to see if i can get a loan for an 06 XT since the SF will be doing a lot of sitting around as i collect parts. that's the plan, at least.
