Hi! Have you installed those seats into your SPG yet? I assume you fond some problems to make the base fit to your car?? hehe.. Those 9000 seats have an other base and seat bottom then your '89 car. (At least if you dont have passive seat belts) If your car was 1990 or newer, the 900 seats are the same as in the 9000....and the seats would be bolt on...
