Thanks everyone for all the information.
I re-read the section in the CDROM regarding replacing the lower ball joints and it is now clear that I do not have to use a spring compressor to get in there.
I will try to get the ball joint tool from IMPCO in the next couple of weeks, as the noise in the front end is really bad.
What is the collective experience regarding the rubber bushings in the aluminum casting? Mine look OK, but there is are big washer-like things that prevent me from seeing if the metal centers have separated from the rubbers.
