It is hard to compare new and old frames. The metallurgy is different and most new truck frames have boxed sections. This gives them more stiffness in twisting and bending. Also they vary from generation to generation aND between capacity. The 73 k20 frame I robbed parts from was thicker and seemed harder to cut through than my 66 k10 frame. And the 83 k30 frame was thicker still.
