3/4 ton front swaybar There actually were two diffrent sizes of front sway bars on those 3/4 ton trucks in that era. They had a standard size of 1 1/16 and then they also had a 1 1/4 heavy duty option. I believe that if you have the big 13 rotors on your truck, that it would be considered the heavy duty model, but don't qoute me on that.
