wtf **^%$

I had the same issue when I had a bearing race go bad on me - all I was getting was the drum. Found out what Oklacarcollecto said - the drums are seperate from the center part. At that point I just upgraded to front disc brakes with the larger bolt pattern because I couldn't find the center part. I already had most of the parts so i went ahead and swapped out the parts. Sorry to hear they haven't fixed this for you yet - it was years ago for me!
