Cannot help from Australia, even though Isuzu are building up their presence here.
The VX is a "grey import" here, and they won't get parts even if you go in with the part numbers.
If it fits some other Isuzu, no problems.
I think we need a direct contact in Japan - perhaps a friendly English speaking Parts Manager at one of the Isuzu dealerships.

Thanks PK. I like your thinking and advice. So......is there someone from Japan watching out there who would volunteer to help us? We are very polite, nice folks just looking to keep our VX's running/ looking OEM- beautiful style.
