From "La Nouvelliste" and "El Informador"
24-2-1962 Haiti 3-0 Mexico 2nd Division selection
27-2-1962 Haiti 1-1 Mexico 2nd Division selection
From La Nouvelliste, I got the impression that the Haitians were not aware they were facing a 2nd level team until after the first match was won surprisingly comprehensively.
My "rough" files had listed 14-1-62 Haiti 1-1 "Mexico" and an apparent duplicate 14-3-62 Haiti 1-1 "Mexico" - with a note to check up on these later...
Seems based on what you've found, that both of those are mistaken.
