Thanks for the reply. I was hoping I could replace one at a time but I guess not. The rag joint looks like it's hard to get at. Right now the front nose of the car is off, so are the doors and the interior is stripped. So I guess that by doing them all at once and disconnecting the steering the body will be able to move away from the sub-frame. Part of my problem is that I have lost all of my patience over the years.
