i put some new seats in mine yesterday, its a dynamique though, you may need to take out the seatbelts which i did... in fact you probably will, that can be quite fiddly. As your car doesnt have airbags in the side, then no worries about that, as i think the front ones wont be effected when playing about with seats. be warned though, you may need new subframes... and i had to go under the car to remove my seats.
good luck though, im sure therel look sweet.
