Ewie, there is no problem and in fact no mistake in yours. This is work in progress and in many cases including this one we see problems that are not there because of insufficient information.
It is not accurate to say there was a different production sequence for RHD cars. All Japanese cars are RHD, and I was noticing that according to the Japanese [aka JDM] production sequence your car might have been manufactured round September 1991
if it was part of the Japanese production series of RHD cars. Which in fact it is not, yours is part of the Australia production series, and they have their own production series of numbers, and based on that sequence June 1992 is correct for your production number.
Apologies, I never doubted your information, it just needed to be placed in the context of the correct production series.
Joe
