The speedway Monaro was also driven by Steve Millen at Waikaraka Park. I doubt that JR ever raced it anywhere else but Waikaraka and Forest Lake.
And yes, apparently ended its days as a streetstock, but considering these car were built on the original floor pan and had some very hard racing it wouldn't have been much use for anything else.

Here is Mr Millen showing Ray Wright that there are two laps to go...............


And the Capri that Rod and Steve Millen both raced at Waikaraka Park with much success. Steve also drove Midgets at Western Springs.
