The way I find those parts is to go to Rock Auto's site and look the parts up.
This link should get you to tie rod ends. Then I find the brand I like, which is usually Moog, get the manufacturer's part number, and then go shopping. Sometimes I buy from Rock but other times from other vendors, inc Amazon. And that is usually based on price and availability.
