I bought the shades for a 1979 Hurst Olds on the suggestion of another Cutlass owner. These shades should fit any G body GM from 1978-1988 with GM t tops. I don't know why they are not advertised that way. I just would have liked them in another color choice other than Black. My interior is Camel but I guess black matches everything. They fit my car perfectly and really keep the heat out. I leave them on even with the t tops removed. Easy to store that way.Glad I found them.
