Re:SI Seats question.
 

i was just kidding about riveting them but i have both sets of runners both si and dx so i will make it happen somehow, also i will drill the seat before the car.

I've got a set of old Prelude Si seats (89 style), but they don't fit either... I'll have to find some Civic Si seats...

All you have to do is put the si seats onto the seat pan for the origonal seats i jst got done doing that.
