I'm not sure I'm understanding your question. Stock location for what? Rear end? Front ball joints? You mentioned 'drag' car. Does that mean a true drag car, or a sometimes street car too? Drag cars can get away with spherical rod ends, which work well, don't bind, and are adjustable too, but you wouldn't want to drive it to work everyday. Several manufacturers offer all the components, although I can't say that they all offer a complete kit under 1 part number. If you're going to see any street miles use bushings. The ride is much more bearable if you're old like me, and they are quiet. Most people (myself included) use poly bushings. I used them because they were cheaper, but the do deflect less too, plus they last longer than the rubber ones. Nowadays most have a grease fitting the really helps to keep them from squeaking which used to be an issue. To move the ball joints around takes pricey control arms. What kind of budget do you have to work with?
