Prelude Seats into a Civic

[Eddh]

I have managed to aquire a spare set of prelude seats from a spare 4th gen that my mate had knocking around (write off caved in roof etc, think it got rolled about twice or something lol), I want to try and put them into my 6th gen civic EK (96-00). I have already had the Civic seats out and tried putting these in and have realised that they arn't going to bolt straight in. Has anyone ever done this or knows where i can find a guide on fitting them into an EK?
