I have successfully removed both control arms from the driver side of my 1970 GT. The upper control arm has been sandblasted, painted and is ready to mount the new bushings. The lower control arm is a different story. The ball joint has been removed and the control arm sandblasted; however, I've got a problem. I can't remove the cast iron piece from the arm because the inner sleeves appear to be permanently attached to the cast iron. Both sleeves are seriously pitted and deformed so they will have to be replaced. How do I remove them so that I can replace with new ones from OGTS? I hope you guys have some great ideas because I'm clueless.
