Hi ive got a friend who's trying to add bucket seats to their car and she says that its difficult to find low position rails and i was thinking maybe other cars would fit or fit with modification...like ep3s? dc5s? etc? any suggestions...

 

ep3/dc5 will fit with slight modification (making one bolt a bit bigger)

 

Wedge Engineering makes custom brackets for 01-05 civics.
I am in the process of doing this right now, it is not a job for the weak of heart. It has been a pain in the *** from the start.
