Bench tested it today. It's scary fast.

Verdict from my pics came in from Warn and they are not concerned with the parts being knock offs.
Second 8274-50 set came in and will be ok, not perfect, but the housing seals together better than the last set so I'll use them.
This company works on castings all day long so I think it's in good hands. They will media blast the parts first then grind, then fill the crack at the mounting tab.
I'll post pics when I get it back.
