I have a suggestion, loose the CD player. Actually I have a 97 accord and installed it myself. I left the factory head unit in the dash which I don't know how similiar the dash is or if the CD player is the same size, but the fit was extremely tight. Basically the lip on the sled is over the front of the head unit and the dash so that the Riocar faceplate protrudes from the dash a little. It doesn't look bad but I did find that there was no place to actually attach either to the frame behind the car. The original head unit was screwed onto the empty slot which was screwed to the frame. It rests on the frame inside the dash and is very snug in the front so that it does not budge without a good deal of force.

I hope this helps.
