Ok, so I've lost a piece of trim/moulding thing off the front of the RX, and can get another from a wagon pretty easily as they are fairly common, but the 3 door coupes are not.

I am wondering if they are all the same.

Its the bit on the front left fender. You guys driver side. Goes between front bumper and wheel arch. I think its attached with clips... Well thats all thats left anyway. Black with gold stripe

You can see what I'm talkin about hopefully. So I've heard the fenders aren't interchangable with rx to anything else, but what about the trim?

The back part of that trim piece is the same for all 87+ EA82s if I remember right. However finding one with a gold stripe may not be so easy.
