I'm confused when it comes to interchangeability. I have an '89 CRX Si USDM and i bought the front fenders, hood and bumper from an ef-6. I was told the pieces were from a CRX. Now i would like to know how i can tell if theyre from a CRX or Civic and what exactly do i need to make the switch. I have the rad support and headlights attached to the bumper as well.

Any help is appreciated since i have till tomorrow to make a final decision
