Four links for newbies

im new to the site, and want to know something. I have my truck bagged on leafs. You know the old skewl cheap-ass way. Well I wanna fourlink it. What do you guys use for the end links when you make your own 4 link? Do you just go buy some new bushing and some pipe that they will fit inside of? Or what? I know jason thorbecke sells some end links, but I wanna make mine.
