Chinese brake drum issue???? HELP!

I've now ordered drums from Autozone, O'Reilly and NAPA, all were incorrect. The drums that came in had a lip of sorts stamped around the circumfrence of the axle register that is raised maybe an 8th of an inch. This raised lip will not allow my rims to seat against the face of the drum. Not even close. All old drums that I've seen in the past did not have this lip. All were manufactured in China, probably by the same manufacturer and just labeled differently on the box. 10x2" 4&1/2" bolt circle.

Anyone know where I can order the correct drums from? Preferrably finned.
