I think they were all home-made. Coyote X made a pair for his XFi.
To answer your other question, you need to stay within the same generation to get aero lights that fit ('89-94 for you). I believe the aero lamps from the convertible might swap in, but don't hold me to that. Not the Swift though - unless you're also willing to swap the hood and upper bumper cover.
Seems much easier to get some lexan and make your own, now doesn't it?
