Standard Coupe: Classic Industries offers a lower grill insert for the 1978-79 Standard Grill. Will this also fit the 1981 nose?

yes. All the grills will interchange but the only problem is the cross hatch pattern will be different. If I was gonna change one I would do both that way nuts like me wont go hey you got a 79 grill on a 81 car. We will then be like you got 79 girlls with a flat dash 81 car. :beers:
