hey guys. i bought a new but never installed set of pa racing tubular control arms and k-member. When i received the packages i was missing 1 of the 8 bushings that you get with the control arms. i think they are made from delrin or some other polyurethane. well anyway i asked the seller about them and he said that he put everything in the box so then i e-mailed pa racing weeks ago and havent heard from them since. so i was wondering if replacement bushing for a stock controll arm would work like the energy suspension one. thanxs
