That is a very handy site Alfred
I just found out that my option code 471 is "SPECIAL EXPORT VERSION FOR BAD ROAD CONDITIONS AND OIL BATH AIR CLEANER ON EXPORT VEHICLES", no doubt attributable to the state of roads here down under (not any better since 1966!).
I also have option code 619 which is the Euro style halogen headlights (with integrated fog lamps), plus orange rear lamp turn signals (for Aussie/UK/Italian cars).
