National classes sites

Hi, everybody. I know this is more a discussion forum than a web-search help service, but does anyone know sites with complete (or almost) results and data about the national single-seater formulas below Formula 3 (Renault, Ford, Vauxhall and the extinct Vauxhall Jr.)? I made a long trip along the gigantic web-links-labyrinth, but I didn't found what I really want. If someone gives me a clue...
Ah, the same for Italian F-3!
