Correct drum for 9" drum brakes

Update, the Dorman 610024 is pretty much a exact duplicate of the original studs in my hub, about a 1/4 inch longer and well much shinier (grin). I did find that the studs basically all but fell out with little pressure so I wound up spot welding them to the hub from the back side. I also reamed out my drum stud holes, not as perfect as I wanted but will do. Thanks for the help guys.
