Quit messin' around. Chev Duty has the right sets for 1-tons or even Chevs of the 40s. C-Duty is cheaper. I bought two other sets used thinking I could make them work and STILL went with correct kit later as some thrust bearings were diff and the pins were longer on other years. Same size pins just longer. Yours should have a roller bearing and holder for thrust bearing, and some only have the washers stacked for that. Don't you just love the 1-ton crap for being just a little diff than normal??
