Fumblin,
they were an awesome looking truck and they used very heavy looking and large sheet metal. They did have pickups and the cab and fenders looked like they were from a tractor. A few months back I saw one in a rodder magazine that had been made into a woody sedan. I am not much of a rodding fan but it looked pretty incredible.
