I put prelude seats in my ek, they are not a direct swap but worth the trouble. Three of the four holes line up, one has to be drilled. You can swap the rails for civic rails but you don't get the ride hight of the prelude seats which is much better. Also, the big bolsters are awesome and the seats are mad comfortable. I suggest you just play around with them, doing seat swaps is like an hour or two of work so its worth messing around.
