Ok if your drums were originally on top of the hubs these are 21a style drums. The replacement drums that you purchased were 51a drums which go on differently and this is one of the reasons you are having a problem. You can use your hubs you have with out purchasing anything new by getting the correct drums first and then address the stud issue. Using your hubs with the correct style 21a drums you can marry the unit together by using a new style knurled stud. Using these studs requires you to ream the existing stud hole in the hub out slightly larger to except the late model press in stud.If you are interested PM me and I will give you the stud number. Not a big issue but requires some additional time and effort repairing your booboo.
