Dear xt'ers

Last Sunday I had an accident on my trip to Asia while on the Italian highway. I'm okay and my bike is for the most part as well.

Only a big scratch on the tank, broken indicator, the horn switch doesn't work anymore and the left hand controls are loose because the little pin that inserts into the handlebars broke.

I already ordered a new indicator. But I can't seem to find the part which fixes the controls to the handlebar with the pin insert.on the part it says "8617".
Can someone help me out by finding this part, and also a horn switch?

Thanks a lot
