1992 GMC 1500 headlight differences??
 

Hey, I'm looking at buying a 1992 GMC 1500 305 V8 2WD. The one I'm looking at has 1 square headlight on each side but when I look at pictures of that year and model they show 2 rectangular headlights on either side. I have found some pictures with the 1 square headlight but far fewer. I'm just wondering if the model of truck I'm looking at is inaccurate or if there is another reason for this. Thanks for any information!
