It’s unclear how solid this body is, given the diamond-plate in the back and a patch on the side.

“Rebuilt Buick 231 6cyl. even fire with less than 500 miles. The rebuild was 20 yrs ago and have all receipts. Three speed transmission with the 2 lever transfer case. New Rochester 2 barrel carb and plug wires. Motor runs perfect and is great for putting around in the country, For the street the jeep would require some attention.
Front bumper is plumbed into the radiator for additional water storage to prevent overheatings. Warn locking hubs and believe 538 gears. Have a 4 speed to go with it for extra $”
