Clyde Kusatsu (Admiral Nakamura) is interviewed on ST.com. The interviewer knew Kusatsu had auditioned for Quark and asked him.
My agent said, "They're wondering if you're interested in being in makeup for seven years." Like any actor who wants to work, I said, 'I'll do anything for seven years." Armin Shimerman got the role, and I don't really know how close I got. I know I was in the running because they asked me if I'd be willing to be in prosthetics for seven years.
