third part insurance

NEED HELP finding third party insurance Valparaiso

I am looking for some guidance getting third party insurance in Chile. My truck is due to arrive in Valparaiso the 20th of this month. My wife and I will then start our 6 month South America road trip for our honeymoon. I thought I had everything in order until my customs agent told me she can't find anyone to insure my vehicle because it is over 15 years old. I'm having trouble finding much current info on third party insurance. Wondering if this is just something I can take care of easily and buy in Valparaiso or if it's going to take a lot of effort to get done.
