crx seats will not fit into an ek without extensive modification. period.

the rails on crx seats attach to the bottom of the seat. the rails for an EK attach to the sides. i used to have an ek, and between paul and my sister we have like 8 sets of crx seats laying around. there is no way those seats will go into an ek easily. you're best bet is del sol seats or g3 teg seats.
