Chris, the story behind the wide body, or should i say 'wide body' is that Nissan made cheater bodies for the Japanese domestic racing series, which were 4 inches wider. The legendary class winning 1200 coupe is one of these cars, brought in for Bathurst. The twin carbies & the 5 speed were what drew the attention of everybody, nobody thought that they weren't kosher on the body shell. The car in question is the John Boston owned coupe,
which was the spare car. I can remember seeing the demonstration of a standard coupe rear seat not fitting & them (John & his brother Micheal) having to use a 120y seat because they were running Club Car (turned into Improved Production) not Sports Sedan. At that time Club Car needed full interiors, including centre consoles. I can remember another friend having a heated argument that his Corolla coupe was the poverty pack one & it didn't come with a centre console,which was not true but it convinced that scrutineer. I was running a 1200 sedan so I was OK. I can also remember an event where the scrutineer was insistent all 1200 coupes had a parcel shelf & we all had to get them in or we wouldn't be allowed to race. That one took a combined effort of 4 owners to convince him he was wrong.
