Mark forwarded a linke to Carhenge, an outdoor sculpture just outside Alliance, Nebraska. It turns out a Willys Truck was one of the vehicles used to create it. If we have time, we’ll stop by here and check it out on our way back from the East Coast.
There are a variety of pictures of Carhenge on Flickr. Below is part of one.
That appears to be a 47 to 50 1/2 style truck with the flat front fenders. I see it has the flatter grille.
