I'm not in Melbourne, but in answer to your questions:
1. Out of a wreck is probably your best bet. Never seen it for sale. (Come to think of it I've never been asked this before
)
2. Ditto
3. The kick-panels are made of quite thick card with an embossed pattern in them. If you can't find a set in your interior's colour, they come up OK with vinyl paint.
4. Original vinyl (and it was vinyl, not Elascofab in the utes) is very hard to get. Hopefully someone in Melb can point you in the right direction.
5. Rare Spares, Spectrum Rubber etc
6. Rare Spares (it's called wind-lacing, btw)
7. Geez, was this car a burnt out shell? What happened to the interior? The trimmer (that I can't help you with
) should be able to assist here.
8. Rubber mats only - speak to Martin of Obsolete Rubber Mats (they're Melbourne based, 0412 941 799, or ah.03 9317 8725)
9. Rare Spares recently remade 'standard' and ute/van screen rubbers (they don't have the groove for the stainless trim that "Special" sedans/wagons have).
10. Rare Spares / Spectrum Rubber / off a wreck
Hope all that helps,
