Try doing a google translate search on Yahoo japan for parts for a sunny Excellant,Not sure but South Africa also had some different stuff like that on some models over there,But basically the Sunny excellant range both PB110 and PB210 models were mainly Japan spec models,I remember looking for spares when the Ex Works Sheka Mehta PB 210 was in my posession years ago.Stuff is around and often in the strangest places.
Many early japanese vehicles seem to get manufactured in India as well these days,I own a Suzuki Mk1 GTI and that body shell is still in production in India as are very old 1950's vintage Austins called Hindustans.

Early 1960's Australian Ford Falcons were still being made in Argentina until 1992 so when looking for older car parts scour the world it may still be in production somewhere or at least made much later than you realise.
