In your hypothetical scenerio the arm would move all over the place. Understand that the geometry of the upper control arms coupled with the lower control arms is what centers the rearend. Which in turn limits the side to side movement. These could be used (as titled in Speedway description) as control arm bushings. Please understand that I purchased these to use in the rearend housing for the upper control arms. The upper housing bushings and the lower control arm bushings are the same for a G-Body. Hope this clears up what I was trying to accomplish by using them in the upper housing. If you were to use them for the lower control arms, I dont think it would be budget savey. You would need 4 bushings ($100 + shipping) and have to go through the trouble of replacing the stock bushings in a set of stock (or boxed) control arms. You could purchase new solid lowers for less than the parts and labor involved. But for replacing the upper housing bushings you can't beat the price vs. quality ($50.00).
