Does anyone know of any good sources of information about Brazilian (or South American in general) national-level racing, 1960s-1980s?
It may be the language barrier, but I'm really struggling with finding any sort of concrete information - results, entry lists, championships, press clippings - below Grand Prix level, before the 1990s.
There are a number of drivers I am trying to research, who seem to only exist as fleeting mentions in an article I managed to translate.
TIA
