Welcome to the forum, and PNW Subie fans. Need to get you on an autox or racetrack soon, so you'll fit in better. :-)
If you are in Spanaway, have you visited PIA (Pacific Import Auto, I think). Should be off Highway 7, but dont quote me. I had to use the nav to get there. Anyway, they are a great Subie shop and might be able to help you with sourcing parts.
