My info on this truck is it originally had the buick 322 engine,(replaced with the 409) 6 speed Powermatic trans, the 3 speed browning, power divider, all which were gone when I found the truck. It did have air brakes also. When the guy I got it from found it at an estate sale, the owner told him he could haul logs tomorrow with it if he wanted. It's placard weight read 68,000lbs
