I am in the process of changing out rear upper and lower knuckle bushings, sway bar bushings and links on both sides of my 1998 Eldorado. I also ordered control arm bushings but after inspecting the parts, I realized the wording was misleading (to me) and I ended up with two sets of rear knuckle bushings. Searched the web for the correct rear upper inside control arm bushings. Arm to frame. There don;t seem to be any to be had. Any help would be appreciated.
