More importantly an L34 won in 1975 and 1976 with a banjo, and almost won in 1974 as well, in a far more powerful and heavier car with bigger rubber. The XU1 came so close in 1973 as well, so banjo fitted Toranas either won or came very close in 1972-1976. Doesn't really prove much as Gene says though. We've all busted a banjo on the street!
