Ok.. I found someone that may be able to help you. His name is John Bloom and he's in Eugene..
heres his website.
http://www.oregonoffroadsubaruclub.org/
his email and phone number are on there.. I know from experience that emailing is not the best way to get ahold of him.. calling him is the only sure way, as he is a very busy guy.. But hes a pretty good guy and a lot of my friends have done business with him and some of them offroad their subarus with him.
Also, another great resource is
www.ultimatesubaru.net . its the best place on the web for old school subaru information. a whole bunch of us subaru types all in one place
There are tons of people on that board in washington and oregon.
Forgot to mention.. John runs a Subaru only- custom shop in Eugene.
If you have trouble with any of the contact info, let me know and I will get ahold of him for you... Just email me at czaharris at comcast.net
Tell him Calebz from the USMB sent you.
