Do you have a parts book or microfiche that covers your model,
and/or do you know the correct part numbers for these ?
Essential for chasing up obscure stuff that no-one knows by sight.
A pic of what the old ones look like may be helpful too, if they are still recognisable.
Or a pic of the housing where they came from.
You tried the main Honda importer where you are ?
Honda used to have a policy that no older part would go unsupplied,
and has a central warehouse someplace that must stock a lot of stuff !
They airfreight as/where required around the globe, and this (apparently)
costs (much) less than stocking stuff all over the place.
Its extremely unlikely car parts could be substituted, there must be squillions of varieties of rubber bits,
but an eagle eyed parts salesman may be able to advise. They are a vanishing breed these days though,
its all new hires and a computer that knows everything - but refuses to give away secrets !
Sometimes the wreckers are a useful source of such stuff, although finding a low mileage back wheel etc
for the right year/model may be wishful thinking ? But you can ask...
