Be quite tricky finding that info Michael, JR did race it a LOT in both NZ and Aus right up until the arrival of his XC Falcon hardtop, in 1978. And in both NZ Saloon Car Championship races, non championship races, and Aussie Sports Sedan races. He did win the $100,000 Marlboro series in Aus in 1976 (I think) and the NZ Saloon Car Championship in 1974.
