Last week a couple of us went to a neighboring town to look at a gathering of Willlys wagons and a pickup. All of them have been sitting for 20 to 30 years. A couple outside and a couple inside/ outside.
The two I am showing here are a 1940s two wheel drive wagon and a modified 1940s panel delivery. The wagon does not have an engine but is very solid. There is another later wagon in a field with hurricane six engine and full drivetrain. Maybe put the two together??
If anyone is interested in these or the 1950s Willys pickup (actually rather solid with a nice cab and little rust) let me know. I believe they can be had for a reasonable price and most have titles.
