Where to buy small crt.5 OEM parts? (nuts/wheels hexes, cross pins etc)

[R00ST]

I sent out some of my stock parts off my crt.5 to a guy who was supposed to be making some wheel adaptors (will withold the name).

Anyway..its been a few months and I sent him my stock parts to help him get an idea of crt.5 part sizes.

In the few months time the parts have gone missing and he is requesting information about stock part prices for replacement/refund (a kind gesture but still a pain for me as I now have to track down parts).

What I sent him:
Axle pins (go inside wheels hex)
Wheel hexes
Wheel nuts

I think thats it... I have been watching ebay but have not seen much. I have tried a few online hobby stores but have not come up with much. They all seem to have the same (very limited) amount of OEM crt.5 parts.

Any help!?!?
