parts only interchangable would be the pre-facelifted crx's 88-89 models.

australian spec crx's will also fit on your current car

SiR front end would fit too, but you would need front bar, front bar re inforcement,headlights,bonnet and hood latch to fit it ( which is a ball breaker and costly)

so go to the wreckers or something, and find a australian delivered ED9 and everything from them will and should fit

if you have any other question's feel free to PM me, i have the exact same car (glassroof EF7 in black =] )
