Note that you may need to replace the strut to spindle bolts (2 on each side). The later ones are torque to yield, only I don't know when GM went with them. Or if they were all TTY.
I also needed to replace the nuts as I needed to use a hammer to get the bolts out. Didn't want to mushroom the end of the bolt so put the nut back on to take the hammer hits.
