He did....though that may have had something to do with the 1987 AGP support race being a round of the South Pacific Touring Car Championship (no idea if that series was sanctioned by FISA though).....there were alot of mini-championships for Group A floating around at the end of the 1987, there had been a plan for an 'International Touring Car Championship' to run at the end of the year in this part of the world.....
Still interested to find out why Brock could run #05 at Bathurst and Calder, but couldn't at Wellington......i'll have to have a look at an RCN from that period, i vaguely recall the answer in there.
Now what would have happened if one of the 'registered' WTCC teams in 1987 had gone for #5. Would we have had uproar, as Brock wouldn't have been able to use it on a Holden? As it was the Moffat/Harvey car had run #5 in their limited WTCC appearances that year, but as they hadn't paid up and registered, they couldn't lay claim to things like numbers (nor trophies even
)
Allan Grice also had a switch, running #3 at Wellington rather than his usual #2.
