Hy The Yeti, welcome, firstly the largest Chevrolet truck in the United States in that year was rated at two tons, in Canada a Chevrolet Maple Leaf truck rated at three tons could be purchased, these trucks were powered by a GMC engine. Does your truck employ two wheel cylinders on each rear brake? If you could provide us with the trucks serial number that would be a more precise way of determining what size of truck you have.
