My apologies, I made a mistake with the dates, so I'll just give the answers.
Nick Rupa did fight for the WBC/IBF Lt. Mddle title in 1997 vs. Terry Norris.
Mistake was Leslie Stewart fought Michael Moorer for the WBO Lt. Hvy title in 1989 not 1990.
And Syd Vanderpool fought Bernard Hopkins for the Middlweight title in 2000, not the late 90s as I had thought.
