Looks like the rear floor bed has been replaced.

“For sale here is what I believe to be a 1947 Willys Jeep CJ2A. Comes with the tub, complete drive train, steering column, motor and transfer case. I also have an extra dash with guages. Missing and not included are: hood, front fenders, steering wheel, radiator, interior parts. No rust as it has been garaged the last 35 years. Frame and tub underside have some sort of rust coating on it. Wheels are good but all four tires are junk. This would make a perfect Rat Rod project. No Title.”
