In terms of Bob Holden cars, there were 2 built from memory of the various Great Race books.
The first is the one that debuted in 1984 and went thru a number of Group 'A' logbooks as it was delivered across the world and back at Spa and Bathurst and the rest of the ATCC... and survived the "dance of the sugar plum Corollas" in '87 to win its class
The 2nd team car, I suspect is the one David Paterson is talking about, a car built for/with Wayne Bell, that became a Group 'A' unit. Here it is at Amaroo Park, in one shot hidden in the shade.. ahhh for simpler times!
