Quote: Mine doesn't have that ridge either. Check your rim, does it make contact there?
Well I'm running stock steel rims- the hub opening on the rim looks like it could make contact with that ridge. It's hard to tell as it's also got a raised portion surrounding the opening. I might have to just bolt the whole thing togther and do some checking, especially if this ridge is found on factory Mopar drums. And this drum I pulled off may very well be a aftermarket- now that I think of it, I don't recall finding the Pentastar logo cast anywhere on it.
