from what i can tell alot of g-nosed cars came from the factory with quite skinny wheels still, so not making use of the flares.
However, watanabes in 14" x 5.5, 8 and 10" were all factory options (the only year i am sure of this is 1973, but i assume that in the years after, this was the case also). I am hoping to eventually get an offical copy of the sports options parts catalog that i can keep in the glove box etc.
This is therefore my argument to police should they ever question my 9.5" rims, as vicroads regulations only state they must b within 1-2" of the widest factory option, without making mention of the country...although i am fairly sure in court i would loose
