unbolt the upper control arm from the body and swing the "fixed" camber anchors around so that you can set it onto of a tire....after you take the original ones out place the new ones in and SMACK that bitch with a hammer so that they actually move up into the slot where they bold up. might take a good hit or two to get them in there cause they are a little bigger than stock ones...when you get the situated in just swing the arm back around into place and bolt them back up to the body....really simple process! been doing them this way for years!
