good point on the bushings brian.
you shouldn't have to take the spindle off the car to do the ball joint.
loosen the nut and either pry the arm down or hit the top of the ball joint with a hammer, if you can get to it.
that should make i pop out of the spindle.
the easier way to get the rivits off is to knock the heads off with an air chisel.
then they can be punched out.
then the new joint just slides up in and gets bolted in place.
