It was Father. He drove the red car at Surfers, in an attempt by AM to put a bit of a fence between him and Geoghegan for the title that year. Moffat said "beat Geoghegan and I'll pay up", and Father missed out by a little bit. He drove the Geoghegan car at Lakeside a little later. Doesn't seem that Frenchy was too upset really. He said the cars were a handful by nature, but didn't really complain too much... pointed to Pete's form in the white car as an indicator of its potential.
Father also drove the works Series Proddy cars at times, including the Phase 3 that the Bowdens have (in its 1971 Bathurst trim), which was yellow for Norm Beechey at one stage.
