Correct drum for 9" drum brakes

My 66 Dart had swedged lugs to the drums. The old drums were toast and I removed the drums from the hub via drilling. The new drums I purchased hit the bottom knurled section of the new studs I purchased, Dorman 610024 (they hit the old studs as well). Meaning the drum cannot sit flush against the hub. What's the deal, is it the wrong stud or do I have the wrong drum? Does the correct drum have larger holes to fit over the stud? If anyone knows the correct part number for the studs and drum when converting from swedged studs I'd appreciate it.

Thanks
