I have a 1994 Cavalier RS convertible that I'm have problems finding seat belts that aren't in such bad shape. The plastic piece that surround the button has fallen apart. I would like to find a set of buckles for the front. The right side is ok but the left has gotten harder and harder to buckle. The left side is attacked to the bucket seat but the right side is attached to the floor. I would replace them with anything that will latch. I tried a set of 94 Corvette buckles but they don't work. Help!
