would 94+ integra seats fit my 90

 

any seats will fit in any car, you just need the right rails. If you get the 94+ seats and take them off their rails, then take your 1990 seats and remove the rails, you can weld your 90 rails to the 94 seats and it will bolt in. Just make sure the welds are good and strong, you dont want your seats coming loose taking a corner at 70 mph!!!
