Just thought I’d drop a few names here of places I’ve found useful in parts sourcing.
Amayama - great prices here compared to local daihatsu parts dealers.
Impex Japan - somewhat similar to Amayama^
Of course there is eBay and Gumtree too.
As for local places; if you live in Perth WA you should always check out Daihatsu Dismantlers.
City Toyota and Grand Toyota still handle all the parts sales and sourcing for Daihatsu since they closed the doors in Australia.
I had a really hard time finding some parts for my rebuild and I’m still searching for some.
I hope this info helps some of you out there looking for answers.
