Rear brake drums dont fit diff dr axles

Hey everyone thanks for the help. The culprits the drums. I dug out the axles from the Charger rear where the drums/brakes came from same thing with them . I went to The Zone and picked up another set of drums and guess what....same thing with those. I guess that what you get when you buy made in China crap. I figured it had to be something with the drums and not the Dr Diff axles I know he turns out some good stuff. Thanks again.
