did a little checking, the 442 model was offered in 80. its kind of odd, some years they had a hurst , and some years they had a 442 package, but apparently those two options werent available during the same years. the hurst was available in 79,83,84 & 88 and the w30 442 was available in 78,79,80,85,86 & 87. the way its listed though im not sure if both options were available in 79, or if the 442 was available late78 crossing over into 79, then the hurst package took over the majority of 79. thats something id like to know for sure myself. just do a google image search for 1980 cutlass 442
and youll find examples of both the black/gold and white/gold 442's . other indicators of a 442 would be W-30 badges an i think also a hurst shifter. keep us posted on what you find out, and post up some good shots of that stainless roof option if you can, id love to see some nice pics of that.
