I have a rear deck cover from an 1989 Integra 5-door. It's the Dark Blue color, and in decent shape, although the center rubber handle has broken off. I am reasonably sure it also fits the 5-door 86-88 as well. If you have a 3-door and are interested, maybe a dealership parts dept. can tell you if they are the same size.
