Suzuki 2 Strokes

For approx 1973 model TS100, I need the air filter insert.
I have the round type air cleaner 'box', but I don't have the insert that holds the actual filter.
A filter sponge would be good too, but if I have the insert at least, I'd be able to make a sponge filter.
Cheers.

In the US, the filter assembly is available from Suzuki.

Thanks for the tip Jabcb, I'll try that part number locally first (Australia), otherwise shipping from US will cost an arm - if not a leg too!
I'll chuck it over to UniFilter, (they're here - in Queensland), maybe they can help.
