nothing changed between any of the 95-05 cavaliers at all besides the 60/40 split seat and the HVAC and radio being switched around. that and the shape of the steering wheel and airbag. other than that all trunk vents and door vents were all the same. trunks, doors, doorpanels, seats, carpet EVERYTHING was the same. besides headlights etc. but thats all exterior stuff. my guess would be on the 60/40 split
