 Guglielmi partnered fellow Sydney rider Billy Sanders in the 1982, 1983 and 1984 World Pairs Finals.The pair finished in 4th place in 1982 at their home track of Liverpool City Raceway in Sydney while improving to finish second in 1983 at the Ullevi Stadium in Gothenburg, Sweden.This could have easily been a World Championship win for Guglielmi had Sanders, who was otherwise undefeated on the day (and the track record holder at Ullevi), not fallen in turn two on lap one of Heat 16 when the Aussie pair faced the out of form West Germans Egon Müller and Karl Maier.
