I am hoping someone could help me out on this. I'm looking for the venues of these 2 championship fights of the 70s for a list I'm compiling:
05/24/75 Miguel Canto W15 Betulio Gonzalez
Monterrey, Mexico (The Ring lists the National Stadium but I could not locate any National Stadium or Estadio Nacional in Monterrey)
12/30/78 Sang-Hyun Kim KO13 Saensak Muangsurin
Seoul, Korea (The Ring lists Munhwa Stadium but I couldn't confirm this)
Any help on these would be much appreciated.
