smallcar.com is in Fife, WA.
I would look for a subaru enthusiast shop more local to you, something that mainly does subaru jobs, after market stuff, etc..
I talk to
https://www.licmotorsports.com/ about doing a transmission swap on my SVX (2 SVXs ago). Turns out the owner was a former SVX owner as well. I ended up not doing the trans swap on the car, but I keep them in mind for future things.
I'd be sure you'd have similar shops in SoCal.
Good luck,
Ian.
