what's wrong with the ones you have? just looking for a freshen up?
I've seen a few threads about '04 Cavalier seats being a pretty close straight bolt in to the seat tracks. Our seats bolt to our seat tracks, no need to grind.
Any ranger our year on up that is super cab will be a direct bolt for seats & tracks. If I remember right, up to 01 Explorer/Mountaineer seats bolt right in.
