Auto Parts: Where can I buy in US ????, address mail, shipping problems

Question
Dear Sir, goo afternoon. Sir, I am writing from Uruguay and thank you in advance for your time. I have a Mitsubishi EXPO 1993 2.4 and it is really a problem to find spare parts in Uruguay, I need an ISC valve because the one I have it is not working OK. i know in the US i can buy it but i do not know how, could you please help me with address, mail or another way to buy it, thanks again, have a nice day

Answer
    I assume that ISC is the idle speed control.  In the U.S., we call this an idle air control.  Rockauto.com has it in three different brands, and can ship it to you.  If shipping is a problem, for some reason, you can use the services of shopandship.  they can get anything from the States to anywhere in the world, regardless of customs and shipping problems.
