That is sweet! Especially for 1st gen owners. I wish 3rd gen got a JDM version so japanese tuning companies can dress it up. But reality is...its north american market only designed by burgers and fries. 1st gen was designed by noodles, sushi and tofu.
Actually this is an old catalog from the late 90's
I am going to guess that most of these parts are no longer made. You can probably find new bodykits and trim items new. Everything else you will probably be getting used at this point.
You can still get brandnew in a box which somebody stashed in a barn. Well, im talking in japan of course. Yahoo japan auctions got a lot of stuff for 1st gen RA1 ody. You just have to be able to read KANJI letters and understand NIPPONGO for that matter.
