HOW COME THEY DONT FIT??
I HAVE A HATCH SI AND I JUZ GOT ORIGINAL EF SIR SEATS AND THE BRACKETS DONT FIT WHAT CAN I DO???

 

search seatpan swap

 

seat pan swap is the best ive had so many diff kinds of seats in my wagon

 

JDM EF seats only fit in 88-89 US seats because in 90-91 we got auto seatbelts. You'll have to swap pans and I think the recline mechanism too.

 

hushypushy is right... the 88-89 rails are under the seats as they are in japan. the 90-91 rails are more on the outside of the seats. you can use the 88-89 seats and rails. pull back your carpet and there should be mounting points you can use. i think you may have to drill one hole. but they can work. just if you do drill the one hole. re-enforce it with something.
