dr 350
Hi there, get them send in a letter by a courier company to the companies address in the next big town you go to. Two washers should not cost that much in customs duties, if anything at all.
I also ride a DR350 (now at nearly 150.000kms) here in Bolivia and I never had the problem you have, but I know it as I have the same problem with my DR650 and this washers are on the way from Europe together with a whole clutch.
If you come to Bolivia, I invite you for a  and food here in Samaipata.
Enjoy your ride.
