Japan is littered with auto junk yards with all kinds of cool junk, even usable aftermarket parts. We used to hit the junk yards before anything else. We'd walk in, ask the property owners if we could look around and pay him/her cash for parts- they always said yes. I found a set of adjustable shocks, lowering springs and a K&N filter once for the Prelude I had (perfect condition), pulled them myself and paid 5000 yen (around $50.00) total for everything. The wrecked Prelude I pulled the parts off of wasn't even wrecked that bad! Oh well. Junk yards for sure. The Japanese go through cars like we go through socks!
