For those not in the know, these 860s were a mishmosh of two existing series of trucks and came to the scene in 1958. GMC stylists took the grill from the 450-670 conventional series (small cab) and planted it on the fat cab 900 series. The result was popular. In fact they were kept in production until 1962, even tho GMC styling for all of its other trucks had moved on to a completely different look. Some of you know even more about this, so correct me/add to it.
