Not trying to muck up 75Dually's thread more but I guess I sorta am anyways.

This is the DRW hub









And here is the SRW hub turned down to fit the adapter.




Both have the lip but the SRW lip needed to be turned down. I didn't measure it before I had it modded, I just brought the adapter with to the machine shop and asked for an almost press fit to keep it hub-centric.
