I have one that's in very good shape. The rubber isn't cracked or spilling out and the hub doesn't have a seal groove worn in to it. It just needs to be blasted to get that orange paint off.
I didn't know the off set ones had a rubber inlay too. I thought it was just the other style. How much you thinking? As post says it might be after Xmas before I purchase something. I'm still working on finishing up top end
